Caught on dash cam - compilation

One of the things that I noticed on these clips that I was a little shocked about is that on clip number 3, (the one where the car stops to let the people cross the road and then gets back-ended by the person behind him (really hard)) is that the people that the car driver had stopped to let across dont stop to help him or check that he is ok they just walk off!! am I the only one that is shocked at this?!
