The elderly can be bad, but I've seen worse among "mature" drivers as well. As a pedestrian, I was attacked twice by two different middle-aged men because I cost them a few seconds while crossing a crosswal,
That's pathetic of them. I don't know why people act the way they do behind the wheel sometimes. You can take two cars in the same place and have them drive to the same destination. one of them traveling at 80mph and the other at 55mph and there won't be a great deal of difference between them in arriving where they are going. For people to go nuts like that over a few seconds because someone is waling across the road is crazy.
