My opinion is that many drivers are mad a bicyclists because there are a lot of cars, not many bikes, but the bikes seem to be ridden by folks who appear to be on a mission to force folks into accepting bikes on the road, its almost taunting, why ride 3 abreast down a busy main road during rush hour backing up traffic. Again, I've got no problem with bikes on the road, provided they obey all the laws everyone else has to. Many don't, but, many do, not enough in my opinion. Why is this not presented by the bycyclists when they are promoting sharing the roads? I've not seen it when I see a presentation. All I've ever seen is bad drivers. I think the motorcyclist was wrong.
