Would it not? I actually don’t think I would mind speeding cameras and the like. Put a camera on every street and auto ticket every car.
Looking even at normal arterial streets, many streets in Seattle are marked 25, but you'd be hard-pressed to find even a cop going under 30 most of the time.
I truly don't understand US road design. The construction of the road and the posted speed limit almost never are even gently correlated other than on a few select residential side streets in a few select cities who have rebuilt streets based on safety studies.
> I remember in Chicago the interstates having posted speed limits of 45mph... the average flow of traffic outside of rush hour was easily north of 70mph.
> 45 mph (72 km/h) in downtown Chicago, where all the major interstates merge
That seems pretty reasonable. I've seen a few places in the US where several major interstates merge and the post speed limit is quite low -- 45-55 mph.
