At the stop light on my commute this morning I saw another bike pull up. It was a Cervelo with a roadie in full LBS kit. I don't normally see anyone on my commute (never on this particular commute) so I said "hi". I got no response (to his credit perhaps he didn't hear or I didn't hear a reply). Rather than stop he proceeds to pedal in large circles across our lane and the opposing lanes of traffic (enter and exit into a development) presumably to warm up his legs. Rather than wait for the light he blows through four lanes of busy traffic (two straights and two turning lanes). He did not cause any accidents but it is certainly no way to represent bicyclists nor the LBS (also where I purchased my monocog which I was riding). This is just kind of a rant with no point.
