Revealing mistakes: When Ken is chasing the Vette on a bicycle, he hitches boosts in speeds by holding on to various cars along the way. At one point, a construction pickup is one of these "boosts." The driver had to honk and actually slow down for the stuntman on the bike to catch up and grab hold.
Continuity: In the car chase at the end, both cars are almost completely covered with dust. When shown from overhead, they are sparkling clean.
Continuity: Ken's first night in Vegas, he goes to a little burger stand, in one shot the cup on the tray is upright, then, in the next shot, it is knocked over and finally, it becomes upright once again.
Errors in geography: At the gas station in Las Vegas we see a 1978 vintage RTD (Los Angeles) city bus pass in the background. And during two other chase scenes two other RTD buses can be seen along the city street.
