So, I have seen this movie numerous times, and really didn't notice this until now. Go to the scene where Seth and Evan are face down on the pavement with Officers Slater and Michaels. Fogell (McLovin) gets out of the cop car, from the back seat. Now in police cruisers, the back rear doors can't be opened from the inside, they have to be opened from the outside, by another person. Also, go to the scene where Fogell, Michaels, and Slater are spinning cookies in the parking lot. Fogell also gets out of the backseat, by himself. No one opened the door for him.
