>According to http://www.snopes2.com/autos/law/eno.htm, we owe many of our modern traffic laws to a man who never learned to drive.

While teaching science and math at Clarks Highschool, Clarks, NE, between 1970 & 1980 I also worked parttime as the deputy marshal. My first duty was to learn all the laws of the village of Clarks, which were recorded in the registry of the villiage town council.
Clarks was platted in the middle 1880's. At the turn of the century a law appeared which regulated the speed of horseless carriages to 8 miles per hour on the streets and 5 mph at intersections. At all times a horse and rider were to preceed the carriage by 100 yards, warning all traffic and predestrians of the approach of the horseless carriage.
