Have you ever sat in an F1 car and tried to change a gear? Do you remember in the 80's when drivers got out of their cars after tracks like Monaco with blood and blisters on their hands? You can't talk about a gearbox / clutch in an F1 car in the same universe as a road cars. A clutch that had to stand up to over 1000bhp, can you imagine how hard it would have been to change gear? Drivers were more knackered, gears were missed, gearboxes failed more regularly through driver abuse.; it's a completely different set of circumstances. It's like saying my Apple Mac has more processing power than a spaceship that got to the Moon; so what! An F1 driver drives what he's given, and they would outpace an ordinary driver in an S-Tronic (driving a manual) because AS YOU SAY it's just one factor of the driving process. People can quote all the figures you want (0.4 secs is hardly a lifetime for revolutionary tech), but Lewis Hamilton would likely beat any of our times on almost any track set in a 'fastest spec' of S3 if he was driving something significantly inferior (say a manual for example!).
I'm in agreement with Dave here; discuss the nuances of the differences, but any useless 'one liners' will now just be deleted from the thread.
