I'm not wrong, Robert. Pull down the headliner and look at what is
actually
there. A real rollbar would be 2 to 3 inches in diameter. Where did
they
hide
it?

Ummmm, you honestly believe that rollover protection needs to be made
from tube?
Bwaaahahhahahahhahahahhahahahhaaaa!


You are a fool. There's no way around that fact.

Here's one way: make the car a thin shelled sphere. Perfect roll over
protection with minimal metal. The point being, it's the design of the
integrated car that defines roll over protection, not some big
Nascar-greaser roll bar.

Which is essentially what I said, Babs.

Are you an old greaser?

Go back to the 1960's with your big metal tubular roll bars. Are there
roll
bars in tanks? Humvees?


Modern cars are made as light as possible to help them achieve better
mileage.
Despite the increasing use of electronics in cars, note the ever shrinking
batteries as an example of this. Bob's car does not have anything in it's
roof
that would eliminate the need for the windshield to be a vital part of the
roof
support system in a rollover.

The windshield is raked at a good angle. If it was in a purely
compressionable mode, it would be part of the structure. However, since a
roll over is not controllable it would tend to experience tensile forces. In
other words, don't count on it.

The Tribeca is built like a tank.
