> notice how many cars have advertising for the dealership on them as stickers or license plate surrounds. Why do people leave that junk on their cars?

I do have a dealer license plate surround for a dealer that's 3+ hours away; we got the car 2nd hand. It's entirely because I don't care enough to change it, as it would cost me money and time.

There's probably the opposite of signalling going on somehow here... where I'd rather people who think that makes me tacky stay away from me because I think they're shallow. ;)
