I rarely see bicyclists obey traffic laws and I live in a town with a lot of bicyclists. The worst offenders are, as you say, the Lance Armstrong type. For some reason they feel they can take up most of a lane for some egotistical reason.

I can confidently say that 99% of people who act like dicks while they ride their $1,500 ultralite down the road are either californians or easterners.
