> I settle for a middle position, which is that the speed limit should be no less than 35 mph on most streets, with heavy mandated use of automated collision avoidance system.

Why does it need to be so contrived when there's empirical evidence from many other countries in the world about measures which do make traffic safer for everyone involved? Why can't the USA look at that and implement what has worked? It doesn't even need to do the heavy lifting, it's been done, just improve measures which have already saved countless lives in other countries...

Or don't and keep killing 30-50k people every year in traffic.
