> Inability to keep the car straight on a 4 lane freeway when there's no traffic means drunk or high. I’m not talking about people who physically can’t keep the car straight. I’m talking about people who are driving significantly faster than everyone else and trying to get through traffic by rapidly switching lanes. > High speed recklessness to me is overdriving your ability to see ahead and react. This varies considerably even on the same stretch of road due to lighting, weather, traffic, etc. Yes it does. It also varies by car and driver, which makes it difficult judge/enforce at scale. It’s easier to create a heuristic that says in good weather, on this stretch of road, 85mph is too fast. Studies show that consistently enforced speed limits reduce accidents and fatalities. They may not be optimal, but it looks like they are safer than the alternatives.
