My neighbor was riding and got hit by a car. The person took off. He got the plate, called the police and they did nothing because there was no witnesses. Thankfully he is ok.
That being said, living in Florida, we see bike riders all day, every day. Most know the rules, but some do not and are asking to get walloped by some unsuspecting old bat (and we've got lots of those here).
I like how some communities are building bike lanes. But let me ask a silly question - why can't bike riders ride on sidewalks like we did when we were kids? It would be safer, no? I'm not a biker - but I would presume it has to do with uber expensive bikes and not wanting to damage them going over curbs and stuff?
Anyway - when I go riding on my Costco special, I ride on the sidewalk. I know there are idiot drivers out there and had a relative killed on a bike.
