But let’s face it: if the car lid would never close if something is in the way, some other dumb youtuber would have made a video about it and here there would be a discussion about how stupid are the engineers to not let the lid close even if a bag in slightly on on the way and the user know what they are doing.
You’re missing the point of a safety feature. The car shouldn’t, by itself, close the lid if something’s in the way. It should allow the user to push it down, or disable it temporarily, to do so.
The point of a safety feature in any system is to prevent unexpected situation from having unexpected consequences, not to be a magic solution that accommodate for brainless people. In one direction, you can make the judgement call and force the thing down, in the other direction you lose a finger.

I get the safety feature. The point is that here I am saying to the car to close the lid even if something is in the way. I made a conscious decision to do so, and more than one time, so I expect the car to do it. But I agree that it could have been designed in a better way.

Which is exactly what happened here. He made the judgement call to ignore the safety feature (and probably ignored how the feature works)
He did the test wrong because he's experimenting with "safety" algorithms that the manufacturer has provided little-to-no documentation on and is having to come up with answers on his own. Maybe he wouldn't be "doing it wrong" if Tesla hadn't over-engineered every aspect of their piece of shit truck in the first place. This thing is a solution in search of a problem, and it'll chop your fingers off until it finds it.
That was very nearly my exact same thought. Maybe not for curious children with carrot-sized fingers, but for adults, how convenient! Business competitor's body won't quite fit in your fancy frunk? Just while away on your phone for about 10 minutes, let the cat do its magic, and off go the legs! Travel-sized!
Having done my time as an Army medic, this is incorrect. It takes more force than that, but less than you might think. A good 25 kilos with some velocity behind it will easily sever a phalange. Up it to 50 or 80 kilos and you can claim an arm or shin. Mass is the real killer. I’ve seen a vehicle at comically slow speed absolutely yeet someone because it had several tons of momentum behind it.
Casual readers might remember a recent very low-speed collision that nonetheless caused a catastrophic failure due to the tens of thousands of tons of weight. The MV Dali vs. the Francis Scott Key Bridge, if you didn’t guess. It struck the bridge at about 8 mph.
He did demonstrate it that way, specifically with a carrot. And it somewhat worked. The problem is they programmed it to do more and more pressure every time it fails meaning that doing the carrot first actually caused a safety issue. He only moved onto his finger because the safety feature seemed to be working.
The engineer told him the frunk increases in pressure every single time it closes and detects resistance, Judkins said. It’s going to assume you want to close the frunk and maybe something like a bag is getting in the way, which would make it close harder.
