I don't know if its only me, but... when I'm driving, even back in the days when that was a daily activity and I was far more expert at it than now... when I have to do some thing like parallel park, pass a double trailer semi or make a broken u-turn in heavy traffic... I turn the radio down... way down. It's automatic... I need to concentrate and the radio is a distraction, so I reach over and turn it down, or off, without even thinking about it. Until now... hmmm... I am a professional musician and uber hard core music lover. Music plays constantly in my home, office, and elsewhere... but not on my bikes. I've never been remotely tempted to listen to music or talk or self-empowerment or language learning media while vehicular or recreational cycling. Can it be done? Of course. Do I have any opinion about others who do it? Nope. I have more reaction to people that salmon against traffic. Should a poster with over 2000 posts know how to get the information that they are seeking more effectively than to *cough* troll *cough, cough* the Commuting forum for a reaction? Most definitely.
