Now is an opportunity, perhaps first in ~100 years, perhaps last, to recover the streets for unaugmented humans: slow down cars in urban areas, increase qualifications for humans to drive, eventually ban human drivers entirely, leaving only automated vehicles with enough sensors and going slowly enough to reduce auto-related deaths for pedestrians and passengers alike to zero.
let's make walking and biking cool, but not at the expense of fast personal transport (cars). the best solution isn't to try to slow down the cars but rather to make mixed-use urban areas the default so that walking and biking become the norm. you also get all kinds of other benefits with that (less traffic, healthier air, more fit people, etc) i agree that driving qualifications should be more strict, but probably i…
hopefully you're not suggesting that cars should be travelling 50km/hr in mixed-use urban areas? Because "slowing down the cars" is a synonym for mixed-use area. That's the same thing, if you continue with car-only roads there's no need to slow down the cars.
