[Spridgets] Rollbar and Spridget Safety

[derf]

I think that law also has provisions for the windsheild frame
supporting the weight of the car if inverted.
I believe a roll bar is mandated if the windshield frame can't support
the weight of the car inverted.
If you gently turn a Miata over and put it down, the windshield frame
is supposed to remain intact.  But, if you add any forces associated
with momentum, the frame will collapse.
