That’s funny you don’t want that on cars, but that essentially is positive train control.
Los Angeles and California is experimenting with a road diet. Whether you agree with it or not, one of key premises is separation of pedestrians and bicyclists from motor vehicles. That’s good, because IMHO, pedestrians and cars don’t mix.
Walkability is great. Mobility is better. I enjoy a couple cafe, ice cream shop, and grocery store in walking range. I don’t need a department store, clothing store, fast food, home store in walking distance.
