Yeah, it turns out humans be humaning. We are not robots. You have the option to safely operate a car on your own but if you so happen to have an issue where you cannot operate one safely in the moment, the safety features help you out. You can still operate a vehicle with lane assist and not even notice that it is enabled. You also have the ability to turn it off. You can also still operate a vehicle with adaptive cruise control enabled and not even notice it if you are shaky operating the vehicle properly. These features do not prevent people from operating a vehicle safely on their own. They are there because a fuck ton of people cannot and never have been able to. The past driver mortality rate which was higher when these safety features were not an option is clear evidence of that.
Again, if you are indeed a robot and have never had an issue of going over the lines or going above the speed limit or ever checked your rear view mirror at an inopportune time when someone in front of you is slamming on their brakes, you can still operate a vehicle just the same as you would if they were not there. Hell, you can also simply disable them. But those safety features are there for the rest of us that recognize that shit happens.
Now I will certainly agree that many people should not be driving. I believe that you should have a hell of a lot more practice than six months of driver’s education and passing a very simple test once to be able to drive for the rest of your life. I also recognize that driving is a requirement for many people to work. I welcome alternatives to driving but it is not a reality yet. The increase in safety features helps minimize death and injury in the current reality.
