> I wonder if we'd see speed limits increase if everyone followed them as-posted? Because right now there seems to be this assumption from both sides that everyone is speeding, so they post 70 because they want 80, or 25 because they want 30, etc. If there were speed limiters, it would probably be reasonable to increase highway speeds in places where they are excessively low, but to also enforce the current speed limits on residential streets as hard limits or even lower them. This would massively increase safety while eliminating any concern about speeding tickets at normal highway speeds that people actually drive at.
