JF Ptak Science Books Daily Dose from Dr. Odd
In general I’m not in favor of left turns for autos in cities of a size where traffic congestion is an issue. It seems that from a main thoroughfare that three rights should make a left, easy congestion in the center of a busy street, eliminating lines of cars waiting behind a left-turning car waiting for a break in oncoming traffic, and so on. This semi-crackpot notion was just sparked after seeing this As Seen on TV-style pre-televsion promotional for an artificial hand for a left-turning hand-directional 1916 automobile. The hand is actually illuminated, which would have made it more effective than a stark hand in the night. It seems that they were just about <this close> to figuring our a less mechanical-anthropomorphic and more elegant solution than the illuminated artificial hand-held hand.
