My 4yo ds is an avid 'driver' - so I just put my hands behind my head and control the gas pedal while he 'steers' . . . it can get a little jarring, but his sheer joy is totally worth it. It's imagineered so that you can make it through the entire ride without even touching the steering wheel, so no matter what your kidlet does, it'll be fine. Have another adult take pictures - you with your hands completely away from the steering wheel will leave no doubt as to who is driving.
