As I drive my car along the traffic-clogged streets, I often notice that there are only a few pedestrians on a whole block of sidewalk. Clearly, sidewalks are under utilized and should be eliminated. Many car-centric towns do not have any at all.
I am sure that all drivers would exercise the utmost caution not to kill or maim a pedestrian or bicycle rider when speeding along the new traffic lane, peering out through blacked out windows while they fiddle with an infotainment system and talking on a smart phone.
If a bicyclist or pedestrian feels terrified, they should just stay home or call Uber.
