I can't tell you the controversy this subject had on another forum I frequent. It ended up with members boycotting the forum after some VERY heated debates.
I'm working in Australia after living in America and one thing I am amazed at here is the fact they allow cyclists on the freeways (sometimes in very large packs). It's REALLY dangerous IMHO. I know bicyclists are entitled to use the road as much as anyone else but thats asking for trouble - and not the cyclists fault either.
