> IIUc in a lot of cases, they can now know speeding was a factor because (ironically given this post's topic) the black boxes in the vehicles involved plus nearby surveillance tools the vehicles passed or had an accident in view of give hard evidence someone was speeding.
Base rate matters though; for example if literally everyone is speeding because speed limits are too low then every accident will involve someone speeding.

is that really the case though, or is it people are so self involved that they feel they are too important to have to move that slowly? Just because everyone else is speeding does not automatically mean that faster speed is safe. It could also just be that people are assholes and they do what they want.
IIUC it's mostly that speed limits are set a little conservative relative to average road conditions.
The tongue-in-cheek way it was explained to me once was "the highway isn't 70 because you need that. It's 70 because the trucker driving sleep-deprived in a light rain who doesn't know his left tire is about to blow needs that."
