In answer to raven1822, the BMW M3 SMG doesn't have a clutch pedal. I can't really se why we need semi-automatic gears as there is nothing wrong with manual ones. If you are a racing driver and you need to be able to shave a fraction of a second off gearchange speeds then fine. All most road users ever get from a semi-automatic is a burnt clutch plate every time they try a three point turn.
