roadworthy?

My mind has always mentally added a hinge halfway on a tail that allows that part to move up so you don't rip the whole thing off the car.
The tail is only deployed on the highway,where ground clearance isn't an issue.A cruise-control logic could operate it automatically.The driver would do nothing.
The rigid lower structure eliminates any tendency towards a Karman vortex street-type vertical oscillation.
I simulated the underside support for the envelope on the T-100.It was fine at highway velocity.

It's my experience that it's roadworthy.
