The [original] Tesla Roadster is awfully close to a conversion.

Agreed about vehicle dynamics. The candidate I proposed have a low CG, low unsprung weight, an electric rack for low-speed control, and has added torque vectoring since I've driven one.

I'd add ingress/egress. I have to put my elbow on the windshield to lever myself into and out of the XFi. The FUV step-over height is less than my bicycle.

Also -- The sweet spot between a motor scooter and a cage. It's called the 'upper frame' instead of roll cage because lawyers. What isn't open is aerodynamically optimized to shed rain water.
