Man, I really want to see this. As a custom car lover of almost anything that looks awesome and somewhat out-of-the-box, I can see this thing being amazing on a rally track where they have max roofline heights for participants.
Well - I didn't mention that is my motivation. I've been working the SnoDrift Rally up here in N MI for years. They also do a summer rally and I've worked that also. I work sweep - the cars start the stage - when they are all gone the doctor rally car leaves, then the sweep truck. You have to go fast as they can't start the next stage until the sweep is finished. I was timed in one stage a few years ago and was 25th out of 60. To be fair -- many of the competitors are 2WD.
