Thanks for such a thorough playtest, numbers and cause included! You were right: a key let go outside the game's frame never reached the game, so the car stayed on full throttle. The game now lets go of every key when it loses the keyboard, as you suggested, and the fix goes out in the next update (0.3.3). The camera ending up inside the car after a crash is noted too. And yes, the pack does not wait for anyone at GO :0)
