A good way to learn starts on an incline is to find a parking lot with speed bumps in it. Then, maneuver the drive wheels so they're on the upwards incline of the speed bump. Get them part way up, pull the parking brake, let the clutch out until it 'lugs' (rpm drop, in severe cases the headlights dim
, slight vibration) ), then let go of the parking brake, and try to keep drive wheels on the incline.
Another variation is to drive onto the speed bump in the same manner, and to hold yourself there by using the clutch and gas only, no brakes. you really get a feel for the clutch and the point of 'friction'.
Eventually, you'll get to a point where you don't even have to think about it, and things'll just flow from your limbs in a magical union of clutch plate and fly wheel.
I think..?
