Not entirely true at all. Many different companies, both games developers and race teams have put this to the test many a time over. 90% of all drivers who come from sim racing, fail really hard in real life. 90% of all drivers who give sim racing a go, fail really hard, I'm no exception. They are both extremely different, so much so that it is like comparing jumping on earth, to jumping on the moon. When you switch from offline to online, or vice-versa, you have to learn everything again. You cannot learn how to go quick on a sim, only the track layout. All markers are placed in different places, in different scale. All forces are different, some more exaggerated, others not enough. All inputs are different, in feel and amount needed. All outputs are different, speed, G, yaw, body flick, chassis flex. You cannot compare a game/sim to real life, it never worked before, I'll be dead before it will. But If you want to try to prove me wrong, the Ginetta G40 is an entry level semi-pro GT car, for a days testing/trackday it costs £350 (last year). For a trackday or testday you only need a drivers licence to be allowed in the driving seat. If your paying, I'll gladly show you how different they are, and I'll even give you some lessons to boot.
