I've never designed a bicycle, so one day that would be fun to do.
I would design any vehicle, but probably least likely... a minivan.
If design isn't profitable, then it's art.
We have to control our battery development and testing.
One of the things that I think nobody's done yet is really taking advantage of the electric powertrain layout, which of course, means you don't have a gasoline engine in the front and you don't have a gas tank in the rear.
My view is that we will still have many different categories of cars in the future.
