CarSim
practice your parallel parking
(click inside the flash window so that the buttons work)
Controls:
space - brake
arrow keys - steer, gas/reverse
(if you hold Insert, the steering wheel will stay as is (instead of auto-centering)
Hint: I think it's best to hold Insert and do everything VERY slowly (i.e. tap up/down arrow once, then use space)!
