My Roadster has been in a few parades. Electric cars are generally great for parades because they are quiet, don't pollute, are easy to modulate at low speeds, etc. Unfortunately, despite the fact that the Roadster is a convertible, it is hard to stand up in it without standing on the seat as the windshield rakes back over the floor. The pano roof on the Model S makes it a perfect parade car. Just open the roof, slide the passenger seat all the way forward: Step in to the back seat, et voila, you are parade-ready. Lots of room, things to hold on to, no leaning, etc: I think it's clear that Tesla has the lucrative parade market all locked up.
