He's really impatient.

The identity of this fed-up bulldog left in an SUV is unknown, but it's pretty clear that he has little tolerance for his owner's lackadaisical schedule right now. The real question is whether he knows leaning on the wheel will make that sound (my guess is yes—dogs aren't that bright but they can often pass the "if I touch this and it always does the same thing I know what will happen if I touch it" test). It could just be that he wants to look outside, but my hunch is that he knows his owner will come running back in embarrassment.
