JRA

A successful change is the right turn on red. I can remember dire predictions that the right turn on red would be the end of civilized society. At least in some ways, the change was successuful (at least until some people began using RTOR as an excuse to run over pedestrians).

Actually, the rules of the road have undergone tremendous changes in the rather short time since automobile use became common. It's only about 100 years since driving on the right (or left, as the case may be) became the norm. Historically, that's a very short time-- a short period during which there have been many successful changes to the ROTR: yield signs, stop signs, electric traffic signals, laned roadways, left turn lanes, RTOL lanes, to name a few.

The suggestion that the ROTR have a long established history, that they do not change and that they have achieved anything approaching a state of perfection is utter nonsense.
