This is part of my problem with speed cameras everywhere. I respect the idea, but speed limits many places are too low given that roads and vehicles have improved significantly and they have not changed much to keep up. I would be all for more appropriate speed limits and better enforcement of speeding - and congesting traffic by failure to yield to faster drivers behind you.

While car safety has improved[1], for places where people still walk regularly like NY and Boston, going way over the speed limit is dangerous to people that don't happen to be in cars.

Yes. Any conversation like this can be expanded, because limits are only one tool among many that need to work together, and changes in each location need to be evaluated case by case - where divided roads / freeways would be the primary beneficiaries. But that article indicated the larger problem even in the city was infrastructure design and people exceeding speed limits rather than the limits themselves.

In places where we now have a 25 mph speed limit, if modern tech proves able to reduce accidents by 95% because of accident intervention tech / fsd etc in 5-10 years, should we raise the speed limit to 35 even though the accidents would then be more dangerous to pedestrians? Surely the answer in some cases would be yes, and others no. Or since most people drive above 25 anyways right now, should we just increase the limit now and increase enforcement and penalties? These are the types of changes I am proposing, as well as reducing the incentive to speed due to frustrated drivers passing road hogs unsafely, etc by enforcing minimum speeds and requiring courtesy yields as well. Just because you are driving slow does not mean you are not part of the problem.
