Easy Smithers Race (1st Level)
On the last mission of the 1st level, you have to race Smithers through most of the level to get to Mr. Burns' mansion, starting from the nuclear power plant. You can't cut through the power plant itself because a door slams shut, blocking your way. HOWEVER, if you park your car halfway into the doorway (I used the Family Sedan), The door will slam shut on it, damaging it but not destroying it. The rear end of the vehicle hangs out and you can hop right in to take an easy short-cut to the end of the mission without a hassle.
