Breaking News: state that doesn’t value education, doesn’t value education.
I’m finding it difficult to care about a self-destructive pattern by a state known for self-destructive patterns …. And they keep electing people who are stealing what little hope for their future they may have had
This is exactly what dividing the electorate looks like.
Denying people (kids/young people) the protection of the federal government (right to education, informed participation in democracy, ability to successfully leave the state they were raised in), you are playing into their hands.
They want you to believe those states are full of irredeemable idiots, they market those voices to you, and they will take your statement above back home to keep their own people in place. They want you to cut them loose, but more importantly, on a political and often family level they want their own to fear you.
Airplanes don’t have mechanical connections to their control surfaces anymore. They use triple or quadruple redundant fly by wire systems. But they’re that safe because of the FAA, not just out of the goodness of their heart. We need car regulation bodies to be closer to the FAA in stringency.
IMO the biggest difference between standards in flying and driving is the training and requirements toward operators. Imagine having a DUI being a strong indicator that you’ll never drive again, or basic driver training taking 50 driven hours, in addition to stringent theoretical tests.
Or people needing to check their cars for safe operation every time they start it, and omitting it being a crime.
Or a significant percentage of the population being just medically disqualified from driving, especially over 60 years of age.
I’ve always been strongly of the opinion that driving is a privilege, not a right and you have to prove you can properly handle the vehicle to strict standards. These vehicles kill and injure so many people every year because of awful driving and awareness.
Now public transit on the other hand, should be a right.
I imagine firemen/EMS/Cops are going to get annoyed with all the motorized door handles and just start breaking windows when ever they’re responding to something.
It’s no different than a steering wheel and brakes. It doesn’t matter if there’s some advanced electronics augmenting (or even controlling) those systems: there need to be a bomb-proof mechanical linkage as a backup.
Tesla doesn’t use steer by wire, but some other car company do. It’s actually really nice for having a high steering ratio at low speeds and a low one at high speeds to be more precise.
Plus breaks have been brake by wire for years now without mechanical connection.
Brake by wire isn’t really very common afaik. Mercedes had EBC at some point but stopped using that system. It also had the downside that the SBC unit had to be replaced every so often to guarantee a working brake system.
Ford, General Motors, and most other manufacturers use the same general design, with the exception of Honda, who designed a notably different design.
Brake-by-wire is used in most common hybrid and electric vehicles produced since 1998 including all Toyota, Ford, and General Motors Electric and hybrid models.
The three main types of brake-by-wire systems are: … electro-hydraulic brakes (EHB) which can be implemented alongside legacy hydraulic brakes and as of 2020 have found small-scale usage in the automotive industry; and electro-mechanical brakes (EMB) that use no hydraulic fluid, which as of 2020 have yet to be successfully introduced in production vehicles.
The question now is what the other quote was talking about, seems a bit unclear to me. I omitted the electronic parking brake in the quote.
EDIT: As of now I could find references to a total of 6 car models implementing brake-by-wire, two of which are already discontinued: Toyota Prius, Lexus RX 400h, Mercedes E and SL(both discontinued), Alfa Romeo Giulia and the Chevrolet C8 Corvette.
Again, considering the current amount of models on the market, that’s far from common
The Chevy Volt, for instance, has brake-by-wire, but I don’t think they advertise it as such. Most regenerative braking systems require brake by wire to function effectively, because you need to use the regen at higher speeds and physical brake at lower speeds, but only want the user to have one brake pedal.
“Brake by wire” doesn’t mean there isn’t a mechanical linkage, just that the “primary” means of transmitting brake pressure is electrical.
Between safety regulations, liability, the the potential for a PR disaster there isn’t a single road legal car for sale (yet) that doesn’t have a backup hydraulic or other mechanical system – the brakes must work if there’s a catastrophic electrical failure.
I can’t find which, but some vehicles seem to not have mechanical backup.
EHBs can be implemented by-wire, without legacy hydraulic systems and mechanical connections. In such a case, fail-operational redundancy is implemented, allowing the vehicle to brake even if some of the brake systems fail.[1]
EHBs are fairly common, but they don’t preclude the use of a backup master cylinder system. A pure EHB has been a “goal” for a long time since eliminating the master cylinder and linkages would simplify design and manufacturing cost. So far nobody has been able to convince regulators or their legal team they can sell a car without one, though.
Pure electrical throttles have been the standard for a while now.
Goddamit my whole life i thought by wire meant like physical tensile wires, that the power was transmitted through tension in the wires. Never realized theyre talking about electronic systems where the information is transmitted electronically.
Tesla’s retract the door handle for better aerodynamics. So you can’t open it mechanically from the outside without the handle to hold. I don’t know how the inside works. Plus they don’t have mechanical keys, so the lock is already electronically controlled.
Maybe instead of engineering stupidly complex electronic door handles they could just, I don’t know, design a simple mechanical door handle that is also aerodynamic? These gimmick “features” automakers keep insisting on add pointless mechanical complexity, pointless areas of failure that are expensive to repair, and aren’t even something many consumers care about, or in many cases are overly complex hassles they actively don’t want.
I’d be interested to see how much actual power savings you get from a more aerodynamic door handle anyway, but it seems that this could be handled by a simple locking flip down cover over a recessed handle if the savings is actually non-negligible.
A flip down cover may be an option, but I’d worry about ice build up. How do you make sure you can always open the cover? If you add a mechanical assist, your back to your original problem.
I think it’s likely the vibe and aesthetics though that caused Tesla to go with their super sleek ones over some sort of cover.
You add drag any time there’s a divit in the panels. There’s lots of vortexes and disruption that happens just because of how your hand is shaped and where it needs to go.
There might be a better way to do it, but the other car companies haven’t done anything yet that I’ve seen to drastically reduce the drag from the handles.
Customers want range and saving money. If it does that without extra hassle, it makes sense. But that’s still up in the air. Especially with Tesla’s anti right to repair making things more difficult all around.
It’s also completely possible to make entirely mechanical non-electronic flush car door handles. They’re less of a shiny gimmick than the electronic ones, and less convenient than many standard handle types, but are entirely possible to do. You could also hypothetically do a version that is both electronic and manually operable with the same components, entirely negating the stupidity of an electronic door opener with an entirely separate mechanical backup, provided you are willing to sacrifice frameless windows.
I doubt that door handle contribites anything measurable to the aerodynamics of the car. The truth is that musk thinks it looks cool regardless of how annoying it is if anything goes wrong.
I found a 12% figure. Aerodynamics are a primary driver of range, which is a major ev selling point. A 12% drag decrease is huge, because you can carry less battery which means you can have a smaller motor, lighter frame, leading to even more range. So it would be very important if that is true.
The retractable door handle design allows radical aerodynamic designing for the side body panel. Retractable door handles are invisible handles that contribute by about 12% to reduce the drag coefficient of vehicles. Retractable door handles eliminate the issue of airflow bulge creation, air flow turbulence generation, and air flow pressure conservation. The decreased drag coefficient will also contribute to increasing the fuel efficiency of vehicles as there will be low drag generation resisting the movement of vehicles through the airflow.

You can still have protrutionless handles without making them electronically retractable. Just have a spring-loaded metal flap that you push in with your hand
You’ll still get the icing issues, where you need to be able to get in even with a thick layer of ice over the handle. But that does sound like a really good solution otherwise.
That’s just what Google came up with, sorry. I don’t have time to research more right now. I do know a rear view mirror on an f350 has more drag than an entire Tesla, so aerodynamics are not always intuitive.
i agree. and this isnt just a tesla thing. plenty of other manufacturers are going this route, tesla might be the worst though especially the 3/y rear seat release. when the i8 was released i watched a video on youtube where a salesman and a tech were showing the car off. the tech mentioned that in training they kept breaking the emergency release inside the car. if a tech cant get out in training then how the fuck is anyone supposed to use it in a real emergency?
Absolutely. If your car is on fire, you shouldn’t be digging around looking for a latch, you should be pulling that handle and exiting in seconds. This design is going to kill people.
I don’t know if that’s a tesla thing, or just cars in general these days (as I have an old vehicle and don’t ride in many others), but not having a fucking manual door opener seems really, really dumb.
So the pop out handles on evs make a little sense. The goal is to reduce wind drag as much as possible. At least on mine (not a Tesla) you can still interact with the handle without the car exposing it.
Not having a manual way to open from the inside? No way in hell is that ok.
The wind drag on the handles is so negligible youd see a larger performance boost simply washing the bugs off the surface.
Cars aren’t moving fast enough that such short protrusions really matter.
It isn’t until cars start getting to race speeds that aerodynamic forces become … important.
Does it reduce drag? Yes. Is it smart to do so? Not so much. This is like all the cars that pulled out spares to get under the Obama era mpg requirements. Does it increase mileage? Sure. Is it smart to do so?

Engineering stuff in production isn’t peer reviewed the same way new research and discoveries are in academia. Companies usually produce estimates and sell them, and their reputation and trustworthynes is based on the quality of their predictions. I don’t know how trustworthy this research group is in the industry, but it at least seems to be big.

at the cost of… safety (getting locked inside during a crash… first responders being locked out,), reliability (they break enough to justify a class action); and ease of use… the 12% drag reduction isn’t actually that huge. Particularly when you translate that into range extension. 10% reduction leads to 5% range. in the case of a model s, that’s about 15-20 miles per charge cycle.
And I doubt very much that 12% isn’t inflated. The entire article you linked below is a marketing pitch for the people that make said handles.
If it really was that substantial, you’d have seen cars going to hidden/flush/shaved handles back in the Obama fuel efficiency standards era. You know. When they were removing spare tires to get a little extra MPG. (this is also why EV’s aren’t coming with spares. to squeak out a little bit more range. Compared to the door handles… a lot more range.)
Further, the handles don’t have to be motorized. You can have mechanical latches on flush-mounted handles. The entire design started with aesthetics and “cool” factor. which is why people are getting trapped in them and you know, gettingtrapped and dying. yep. “12%”…but hey, you might die because of it.
oh, by the way, the cost replace on of those over-engineered handles? about a grand. I’d rather sacrifice the range, to have a car whose door actually works reliably. but idunno. maybe I’m just weird.
No. Wind drag on handles is most certainly not negligible. Even small protrusions on an otherwise smooth surface can have a significant effect. That effect is hard to model - you can’t just eyeball it.
Drag is proportional to windspeed squared.
Aero matters to fucking cyclists. It absolutely 100% matters to motor vehicles, especially in the context of EV range anxiety.
Just don’t fucking dunning-kruger, FFS. Surely you realise that automotive engineers have specific education that you don’t have. I don’t mind you being wrong, it’s the arrogance that pisses me off.
There's only a small handful of cars that have primarily electronic door handles. Teslas are the worst because opening the door without power is very different than opening it with power and sometimes breaks the window. I think it was Mercedes or someone who has a power lock but the manual release is part of the same lever, you just pull it out farther.
Also wasn’t there a famous video of BMW showing how to mechanically perform every task on their all electric sports car? From car doors to hood releases to way more niche things 99.9999% of people will never use or even know exists?
It was the I8. The techs were talking about all the little things you can do to break stuff on the car because of how insanely designed it all was. The techs kept breaking the door releases, and you need to jam screwdrivers in the hinge for the hood which requires at least two people to open to avoid breaking or deforming it.
Teslas are just overrated they dont do anything better than other ev cars, they were just first to mass market, which is great but doesn’t mean it’s a good purchase today.
I agree with with you. I don’t understand why anyone would still want to use this platform considering that their are better alternatives such as Mastadon and BlueSky. Hell even threads is better than twitter and that shit is invasive as fuck.
People on the platform can generate invites at some intervals and send them to friends. That’s my understanding, while I don’t know for certain as I personally am avoiding the platform due to not trusting Dorsey at the helm. But I’m still keeping an eye on it with popcorn ready.
It’s already been noted elsewhere that this will directly violate Apple’s and Google’s app store policies. The X app should be immediately pulled as a result.
Literally look at how much attention it's getting him!
Never mind the real goal - he's got an established far reaching platform, he doesn't care about those leaving it, he cares about those staying, that's who he's pandering to - the bigots and the companies openly willing to do business with bigots. And he now has his own media outlet that is aimed directly at them.
People think he's just some clueless manchild, and while he is the latter, he's definitely not the former, he knows exactly what he's doing, and that's building up an empire to secure his power indefinitely.
The LDS church is a force of evil in the world and $1 million dollars (0.002% of their annual proceeds) is pretty cheap for an ad to control the narrative.
Many religious groups use their charity work to distract from their manipulative, self-serving activities and goals. LDS isn’t even the worst offender, but they’re up there. For my money, the Catholic Church is by far and away the most evil religious organization on the planet that isn’t a straight-up terrorist group. The shit it has done throughout its nearly 2,000-year history and the negative impact it has had on populations around the globe is staggering.
I look forward to a day when major religious groups have no foothold in developed nations due to education and acceptance of secular culture and values, but sadly I don’t think I’ll live to see it.
There are different types of average, median being one of them. What you are thinking of as the average, is probably the mean. Median, mean and mode are all types of average.
Trump has made a great litmus test for shitty humans. They even wear hats so we don’t have to waste our time trying to find out their beliefs through dialogue.
Half of all people are dumber than the median. I am assuming the mean is actually higher than the median so chances are way more than half of all people are dumber than what people normally think of when they think average.
They’ll take it as far as the pollster wants ask. It’s not really about what they believe or say, it’s about unwavering support and owning the libs. They know they’ll never be tested where they have to choose, so it’s just a big game to them.
When you deeply immerse yourself in the multifaceted realm of political analysis and personal character judgments, it’s intriguing to observe the vast spectrum of perceptions surrounding a figure as polarizing as Donald Trump. Some individuals, after a careful and considered examination of his actions and statements, might arrive at the conclusion that he embodies a form of genius, a distinct capacity to navigate the turbulent waters of political and social arenas. To them, it appears as if his trajectory has been characterized by a series of unerring decisions, each one seemingly infallible in its own right. Now, the nature of human judgment is inherently complex, rooted in a combination of cognitive biases, personal experiences, and cultural influences. So, when one posits that they’ve never witnessed Trump commit an error or hold an incorrect stance, it speaks to a deeply held conviction, one that transcends mere observational analysis and delves into the realms of personal belief systems and interpretative frameworks. It’s crucial to approach such assertions with a balance of critical thought and open-mindedness, recognizing the vast tapestry of perspectives that shape our understanding of political figures and their legacies.
I’d call it a “novelty” or “gimmick” account because a “meme account” should post memes, but yeah. Either it’s using chatGPT with a prompt like “write some bullshit about X in the style of Jordan Peterson” or it’s actually Jordan Peterson posting some bullshit.
