in the following video you see most of the Batmobiles getting staged downtown San Diego for the short 10 block drive to the convention center where they were displayed during Comic Con. The amazing part is that it was at a wide open public area where no ticket or pass was required.
they all got together at the Burbank area Bob's Big Boy partly because of a Make a Wish foundation situation, and partly for the upcoming documentary I mentioned in the beginning of this post. I think that driving these on public roads is likely a thrill for the owers who bought cars that aren't street legal (headlights, tail lights, bumpers, smog, etc etc here in California) and rarely get to drive them... plus to get to drive them with other Batmobiles, that has to be a cool feeling. Small number of people in the Batmobile owners club
