If you consider the rules for human defensive driving as gospel, the safety side of this problem seems to go away. Defensive driving doesn't act based on predictions of what external agents _will_ do, which may have regional variation. It identifies what external agents _could_ do, which does not have regional variation, and engages accordingly with rules and physics e.g. by making sure that the vehicle always has a safe escape path if it needs to stop abruptly or swerve to avoid a collision.
- withinboredom 6y agoIn the mountains of Virginia, you are lucky to get 6 inches between two bumpers at 55 mph, especially up by Roanoke. A defensive driving tactic might get you killed because you’ll have to literally stop to get more than a car length in front of you for longer than 1s. Regional driving behaviors are to be expected, and they expect you to do the same. If you don’t, you might cause an accident. Humans are good at this. Machines, not so much. I’ve driven around the country for several hundred thousand miles. Different parts of the country do things differently.
