Well that wasn't fun but I fixed both issues.

I have just one word (ok 2 words)

Parking Brake!

I was 15 and messing around in my sister's boyfriends vw bus.

I thought it would be funny to give him a start and turn the key he left in the ignition.

It lurched forward a foot, which was 3 inches shy of the car parked Infront of it.

I booked it out of there in a hurry!

I would much rather have something to prevent the engine from turning over while in gear and/or without the clutch depressed
