The speed limit is set to 55MPH because the road services vehicles that weigh 600lbs all the way up to 80,000lbs. "Safe speed" is not a single universal number for a given stretch of road.
The laws even acknowledge this, as if the weather is extremely unfavorable, you can be pulled over for driving _at_ the speed limit as it will be declared "unsafe speed under given conditions."
This doesn't even approach things like construction zones, traffic accidents and other roadway hazards that can't be flagged in a way for the automated system to recognize correctly.
Again, That's why I said it's important to have a frank discussion about the general public's tolerance for risk. Otherwise, whatever authority is pushing for speed limiters under the claim of "safety" is just unintentionally taking an authoritarian approach.
> A 26,000lb vehicle, going down a 5% grade, with brake failure, goes whatever speed it pleases.
Don't get bogged down by corner cases. This is why there are runaway truck ramps when this is a risk.
> The general public, famously, does not have the skill set needed to make correct measurements here
That is how authoritarian leadership justifies itself. You clearly do not have the maturity to be part of this discussion if you have to resort to authoritarianism and "ends justify the means."
