I don't know if I'm being lazy and not reading properly, but I haven't seen anyone making this explicitly clear; give a little bit of gas first, then find the biting point. Then INCREASE the gas while releasing the clutch. It should be done smoothly; while you're learning, try and take a couple of seconds from the time you start coming up from the bite to the moment that it's fully released. The speed at which you move your feet should be consistent, so don't start slowly then all of a sudden snap your foot up at the last second.(Original post by po10tial)
If I do that, there is no way it will stall?
Also, won't I crash into the vehicle ahead?
When is it good to do gear changes?
You shouldn't have to worry about hitting the car in front. Once it starts moving off, give it a good couple of seconds before you follow, unless it takes off at speed thus leaving a safe distance between you both.
But did you bother to watch?
