Continuity mistake: When the insect sits on the windowshield of the car Robin Williams says that the insects can't make a hole, they are safe, then the insect makes a hole, the car drives away creating havoc on the road because of extreme bad driving. The car stops, they get out, then there is no hole in the windowshield.
