I see the point on treating the car light like a traffic signal. But in my mind, red lights lighting up on a car indicate it is stopping. Either way - the idea is not without merit (I really like the bull moose thinking). And folks would learn to figure out the green or red lights.
Hmm - I bet somebody could write 20 pages on why cars should be like boats and have green running lights on one side and red on the other!
I guarantee many more than twenty pages have been written on boat lights. But 160 characters is where today’s in depth analyzers and internet experts run out of patience at not being given a chance to fire an off the cuff slander .
I really do appreciate sober commentary such as yours. Not looking for fight club. Too bad about the cool kids.
