Not sure how people would drive better without stop signs, speed limits, right of way, and traffic signals. But having people look up instead of down would make it a bit better. I am just amazed when I see people looking down at their lap and driving! Might as well put blind folds on. But if they don't have to fear getting caught, maybe they'll install window/dash mounts for their phone so at least they'll have some peripheral vision of the road! Hey, it's FAR from ideal. But with my life on the line on a bike, I'd like to increase my chances as much as possible.

I know this is NOT an ideal solution by far. But consider the alternatives....which are not working so far.
