It would be so easy if it were uniformly enforced with time stamped photos and radar speed cameras. Instead the police treat spreading much like the lobster industry in Maine. Manage to maximize revenue. Don’t catch all the lobsters at once because they would be extinct. If they started 100% enforcement, revenue would quickly plummet.

Obviously biodiversity is good which limits this analogy. But speeding really is bad in some contexts. Speeding in residential or pedestrian areas really kills many many people every year. If they catch you going 45 in a 35 there should be a proportionate small fine, every time. Not 130 USD once in a blue moon or whatever but like 40-50 USD every single time.

But until there is uniform robust enforcement, Americans are going to keep speeding on residential areas with their big ass cars, and will keep killing or maiming tens of thousands of Americans each year.
