It takes a real low-life to pull kind of crap.  I just don't know what to say, except maybe he didn't like her so much after she was all road-rashed and battered.  What a bum.

A similar incident happened with my neighbour - but he did not make it. He was riding with his buddies with just bandana, beaters, maybe torn jeans and of course harley boots. He was an older guy and had this problem of passing out - I do not know the details of his ailment. Apparently, he passed out going 50 miles over a curve, hit the guard rail, and was gone on the spot. His riding buddies did stop (as far as the story goes), but flew out there before the po po or amubalnce showed up. I assumed they called 911 before lighting out of there. Alcohol was definitely involved. Guess at least these guys called 911.

You can get lower... trust me...
