Well i just thought i'd say i found it amusing, and also really liked the drawing style.
The part which triggers the amusement for me is seeing the look on his face, and therefore the way he thinks he's being clever by driving ahead, when in the end he gets his comeuppance. Also, the last frame with the stop sign is quite creepy, i'm not sure i can really describe how i feel about it, but there's a sense of suspicion about the sign which comes with the final frame.
Anyways, i liked it.
