[zshsotuy] Aerodynamic highway car

Create a consumer car optimized for gas mileage driving at highway speeds.  At high speeds, the v^2 component of air resistance becomes dominant, suggesting extremely aerodynamic contours, like a solar car or sports car: a sports-car shaped car without the performance of a sports car (in fact, slow acceleration for better gas mileage).

It's a little surprising this doesn't exist already.  Many commuters have long (solitary) highway commutes, hopefully without traffic.
