I don't have a problem wearing bike shorts or tight form fitting spandex undearwear hidden underneath my cargo shorts or relaxed fit athletic clothing or regular clothing, in fact I do that all the time...I just think it's a very silly thing to dress like a racer and wear fancy costumes with all types of advertisments and sponsor names printed all over it, while commuting in urban environment..."regular clothes" has a very broad meaning and it doesn't necessarily mean a suit and a tie.
