I have come to realise that I know very little about vehicles but I don't feel less of a man for that fact. IMO some that enjoy such things can be quite boring and prone to over-compensating.
EDIT:
Not YOU guys obv.
You know more about vehicles than I do about football (our national sport BTW) and I don't see either as a positive or a negative characteristic.
If you think I don't know, you're more stupid than I thought you were.
