In other news, Tesla is encouraging drivers to drive more dangerously
[language warning]
Unsurprisingly, judging driving behavior without context turns safety into a stupid game

To be fair, I would absolutely agree that "running" yellow lights (instead of suddenly stopping and forcing cars behind to also suddenly stop), and the car's familiar owner parking the car instead of an unfamiliar and time-rushed valet, and defending your legal right-of-way, and not avoiding inefficient and frustrating complete stops at the 95% of America's stop signs which should all be yield signs are all more standardized, more efficient, more predictable, and ultimately safer operations than otherwise.
It is not safer to ponder your way through the dilemma zone and then slam on the brakes.
It is not safer to let some random person trying to park cars as fast as possible to park your car for you.
It is not safer to make up right-of-way rules as you go (unfortunate for the rider who also cannot follow rules but that's their legal and moral problem if a collision happens).
It's not safer to come to complete stops when it isn't necessary, particularly because it encourages road rage amongst the people behind you.
Ultimately what is safer and/or more efficient when it comes to roads and highways is an absolute cluster. Our current rules largely make no sense combined, from any perspective, especially legacy rules which are still lingering and forcing new ideas to be compromised within idiotic boundaries. And then there's the fact that you could re-implement all the newest and most efficient and safest designs and rules you could ever want, but they won't mean squat if you don't train people how to use them, which we don't. And we absolutely do not teach new drivers about human factors concepts, or about vehicle and network efficiency, etc. We basically just give them the keys to a death machine and hope they can figure out how to read all these extremely authoritative signs before they run into something.
What I do know is that I've driven a whole lot of new rental cars with fancy lane-keeping and smarty pants cruise controls and all that sort of stuff, and I've driven Teslas with Autopilot (the basic kind, from a couple years ago), and Tesla's system was
way more logical and human-like than anybody else's. Toyota's in particular was heavily over-cautious and infuriating, to the point of people around me getting pissed off, passing me, and causing further problems for my car's system. Being over-cautious is not safe. Being annoying is not safe. In my experience, particularly in aviation, the ideas of efficiency and safety are typically synonymous. But here on the ground we neither design our road systems nor teach our drivers to be efficient or safe.
