I can't tell if the people making these comments about the drivers behind the Tesla being responsible are such defensive drivers that they never leave less than 6 seconds in front of them, or they're tailgaters themselves, or just being mendacious.
There might be a "laffer curve" where increasing the follow distance of other cars and limiting overcorrections would increase capacity, rather than decrease it, at the current level.
If we're getting regular "phantom jams", we're probably following too closely.
3 seconds is a very long time? Also: 3 seconds of turn signal is a clear indication of "i am going to change lanes and fully come to a stop"? And then turning off all signals and coming to a full stop without hazards on is a clear indication of "i am stopping"?
