Synopsis: As John thought-bubbles that Mike should follow the straightest course possible to take Liz and Dawn (who he shouldn't know is with them) to the rink if he is a good son, Mike sets himself up to fail because he wants to see what John's car can do because he's a dumb kid who doesn't know his limits.
Summary: It can go wildly off course because Mike is an inexperienced driver who is going to bomb past an exit. Also, I don't even know if he's legally allowed to drive on the highway quite yet so there's that.
