There's obviously a big difference between driving on the freeway in the desert, where there are no children playing or running over the road, than deploying it in a neighborhood.
To be able to swivel around, I think is really good for a concept car, but in reality, I think for normal vehicles, if you actually look at how a vehicle is designed and packaged it doesn't make a lot of sense.
I think with more electric vehicles on the road, hopefully we'll still be able to drive some fantastic sports cars with big V8s, or V10s, or even V12s. Why not? If we can find a way to balance the automotive world, where ultimately, when we have most of the commuters drive electric cars, then we won't really have any issue with some sports cars driving around.
