It's off-topic, but are you sure you played an actual driving game, and not some kind of crashing simulator? Using a proper steering wheel on a good driving game unlocks a level of play which is virtually unattainable with a controller, and should in no way hold you back.
Gran Turismo/Forza both demonstrate this well, as does (to a lesser extent) Shift and Shift 2, plus a handful of others.
ETA: I wouldn't say that it's a comparable situation though, as the games are designed to be used with a wheel, and the majority of the fast online players will use one.
