Obviously there's no point in all the junk that doesn't have any affect on racing like climate control But it'd be nice to have headlights, indicators, windscreen wipers and pit lane limiters controllable by you rather than auto on/off.
that would be good with planes versus cars versus bikes races in GT5.
hopefully they will add planes in GT5. i wonder Typhhon Harrier how look it is in GT engine. jk.
