Why do car commercials think that parking garages have 50 MPH speed limits?

So I guess this nasty piece of Eurotrash and his significant other didn't really have any plans to exit their car and actually do anything; the driver just wants to drive around agressively at dangerous speeds until he runs out of gas because he's obsessed with a car he likes to pretend is not a mid-level Nissan Blandmobile. If I were this woman, I'd be progressing from amused, to mildly irritated, to deeply concerned once I realize he was leaving the city limits and suddenly barelling through snow (seriously, how many miles out of town ARE they by the end of this ad?) In fact, I'd start to suspect that his ultimate plan was to bludgeon me to death and dump me in the woods so he could have more Alone Time with his freaking car.
