Letting cars into cities was a mistake from the beginning. Cars should be required to park on parking lots or garages at the edge of the city. The only large motorized vehicles allowed within cities should be trains, buses driven by professional drivers, and delivery vehicles limited by governors to the speed of a bicycle. The only forms of motorized personal transit allowed should be e-bikes and scooters that can travel no faster than a human-powered bicycle is capable of traveling. Cars should be used only for getting between towns and cities, not for traveling within them.
