UM...CORRECT ME IF I'M WRONG....

...SPOILERS





......After Charles attempts to kill Tanya and he makes it back to the house. His Mother makes the Trans Am parked in the drive way "Dim" So that the cops can't see it as they arrive. Then she makes herself and charles dim. Later on that night, she sneaks up on the two officers on stake out and kills them. She then takes THEIR car to get Tanya and bring her back. After killing the hell out of pretty much everyone at the tanya's house she takes Tanya back to the her house, only to find a million cats outside. So she rams the police car into the garage. My question is...How did she ram the car in the garage when the invisible Trans Am that she made dim earlier was still parked there? wouldn't she have just crashed into that car.
