Good point. However, doesn't the venturi effect some into play with a narrow, smooth gap at speed, generating downforce? Either way, I can't imagine lift being a huge issue at speeds at which sensible people drive on public roads.

The xB already has goofy handling at highway speeds anyhow, with the combination of it's short wheelbase, narrow track, short gearing, turbulence-generating shape, and a seating position that makes the center of gravity feel higher than it actually is (since the seating position is pretty much above it).

I'm no engineer, so I don't mind being corrected in the admittedly likely event that I'm mistaken.
