I suppose next you'll say I shouldn't ride at dusk/night because I have those upper class HID lights and stuff. Sound to me that you are a little classism in your statements. Just because some one has money spend on cycling doesn't make them better or worse the you. I commute in a full kit on me high priced road bike but this is the only time I know I will have to ride. I would also like to know why you think Bicycle are the ones impeding traffic there are a number of 25mph road that I take, I can keep of with traffic drafting off cars doing 25-35mph it seems to me your problem is one of perspective I hope you will come to realize the flaws in your arguments when you start to commute.
Commuting is not about the bike, It is not about the gear, it is about enjoying yourself, it is about reducing pollution.
Now go enjoy yourself out on the bike, learn to have respect for all and contempt for none.
