That's why some cyclists are adamant about not using a shoulder. It invites a squeeze play like the dumbass motor home driver attempted. Far be it for them to slow until they could safely pass.
Come on Paul. Seriously, you have to admit that there is blatant disregard among cyclists for running stop signs, traffic lights, and not staying over to the side so cars can safely get by them. Many cyclists seem to think the rules of the road don't apply to them, and that's wrong. Explain to me what's going on with the dumbazzed idiots who continually ride on the wrong side of the road. This is your brethren, buddy. Bikes are supposed to obey the same rules as cars, not make up their own rules of the road as they go. As for staying over to the side of the road, doesn't it pizz you off when you're in a car and a much slower vehicle gets in your way and refuses to move over so you can safely get around? Sure it does, but bicyclists often refuse to stay to the side to the right side where they should be. It's no wonder people get fed up with them THEY BRING IT ON THEM SELVES!
