Boy Meets World - Now There Are Cars That Don't Need Drivers!
In the opening sequence, after Corey jumps in the car, they show a lot of different camera angles. In one of the first angles Eric is "driving", but then he is sitting on the side of the door. So basically, you can tell it's fake from the beginning, but somebody could of at least watched the sequence before putting it on air!!
I don't think this is a slip-up. The whole introduction is just a whole bunch of shots put together to give you an idea of the characters. It wasn't meant to look like he was driving and then not driving.
