Just the ones that ride four deep shoulder to shoulder at a leisurely five mph in a fifty zone in the drive lane while blocking traffic AND smugly smirking over their shoulders at the line of vehicles stuck behind them.
Those guys deserve the rage heaped on them.
Not the guys who make a conscious effort to be courteous.

I'd be curious to hear from other FReepers, but I don't know of any state where cyclists are legally permitted to ride more than single file when there is following traffic.

The problem is that cops don't cite them for this, and they should.
