Also, I think the driver deserves some credit. Note how he keeps calm and rational and tells the other adult occupant in the car to not rush out into the road and cause another accident. His first thought is to make sure he understands what is going on behind him. Cool head, good job.

This is the bit driving schools rarely (if ever?) teach and which many drivers never get a chance to think about until they find themselves in a stressful situation where they can end up making dangerous decisions. (And then, of course, most people do not think).
