 During the destruction of Venice, there is a brief shot of the  footwell of the NemoMobile. Shown are three pedals, however, Tom  Sawyer slams his foot on the gas pedal without ever touching the  clutch. This is because, a) The NemoMobile used an automatic  transmission and, b) the pedal on the far left is in fact, not a  clutch pedal, but rather a second brake pedal. By having independent  braking to the left and right side of the car, the stunt driver  could achieve certain tricks not normally attributable to a 22 foot  long vehicle.
