> if everyone runs red lights they will collide with one another

In the same way that if everyone runs green lights, they'll collide with one another? How do you go through intersections?

Red lights rarely exist in the middle of a road just to slow down traffic, they mainly exist at intersections to allow people on different roads to take turns. It's really not a useful metaphor in this context.

Green lights... are synchronized to avoid collisions.
