I'm going to say probably not...but I can't say for sure. I just left London yesterday after spending close to a week there (my first visit there). Wife and I had a rental car and she kindly left all the driving to me (my knuckles are still white). As an American, I've driven in just a couple other times on the left (i.e. WRONG IMO) side of the road -- St. Thomas USVI, Ireland. But, compared to anywhere in the US, London is an extremely cycling-friendly city. I would look out my hotel window during morning/evening rush hours and at the busy intersection below see more bikes waiting for the traffic light than cars. That, and I noticed that no matter where we were motorists were simply very accommodating to cyclists. Most of whom aren't even in traditional road cycling clothing, but rather their work clothing...casual dress, even suits in some cases. So...because of all that...I don't think they'd need to have the reflective logo on the right cheek.Dan
