One of the things I'm likely to start building in my shop is a vehicle wherein each wheel has basically a flight-simulator base as its suspension. It's known as a hexapod; it's basically a tripod but each leg is two pistons. So you have six axes of freedom on it. This will be something that can not only do what lowriders do, but shorten or extend its wheelbase and jump forwards, backwards, or from one side to the other. In an off-road situation it could be rolling at speed toward a ravine and then leap across it.

Dealing with effects, as a job it's great, but with Mythbusters, the stuff we've seen, the stuff we've absorbed over the years, has just been fantastic, and I wouldn't change it for the world.
