Clutch problems, physics at low speed

[Poulpo]

Hello everyone, I already did a post in this kind of topic, but I was only complaining. Can someone do an application to have a more realisitc behavior of physics at low speed : firstly the clutch, then the fact that a car can normaly stall, the fact that automatic cars go at 3-5km/h in first gear without putting any throttle but in Ac it doesn't move, and finally the biggest : if you have an semi auto car and put first gear to second.to first etc... you will increase your speed from 0 to 50 km/h!!! Finally, it's certainly linked to the last thing, but tires made sound when you just pass the first to second gear at 2000 rpm in semi automatic cars.... its so unrealistic for me, I can't understand how it possible... the guy who will do this application will receive 50euro from me (and maybe more from the community
