When the announcer says "Bunch of retards" at the end of the whale show, the audio doesn't match up with the mouth.
Before the gunfight, as the bike-cops (one of whom kneels) order A.L.F. to put away the guns, the moving van driver is first seen to step away and later standing next to them again, as the other one kneels too. Then the womas shouts "Save the whale!" and the shoot-out begins. From that moment, the driver is completely disappeared. The woman drives the van and he is also not among the shot people who are left on the road.
