Green means go.
Exactly!
Thunderbirds are go!
This idea may deserve some thought and discussion.
But.
Today’s mandated turn signals, orange blinking ones, are inadequate.
Forget that lazy, and/or entitled won’t use their blinkers, but that the sleek, fashionable, LED light placements hide the turn signals unless viewed from the perfect angle.
So if existing turn signals are not used or deficient, how will adding some green lights help.
Now consider some drunk driver. GREEN, GO, OOPS!
