I'd rather every crosswalk start a 5 sec timer and flash the lights, and then spikes come up that blow out the tires of any car that's going fast enough within proximity of someone crossing. Driving in the city for anything but uniquely dependant utilitarian purposes should be a relatively rare thing, and building cities in a way that prioritizes it is preposterous.
