Pretty amazing stuff. I've been very lucky that in the 3/4 of million miles that I've driven over 40 years (mostly superhighways) I've only been past a few nasty accidents and never been in one. But I've seen my share of really bad drivers. For a while it was so bad that I installed a 'dash cam' in my car and recorded my trips figuring that if some idiot caused a pilup in front of me at least I could show the cops it wasn't my fault.

Some day I'm going to edit them out and post them on the web, and I won't obscur the license plate numbers.
