Do not drive any car with a urethane set windshield glass without the glass in place. It can cause unibody frame damage, and require setup and frame pulling/straightening to fix it.
The glass is a structural part of your car. (trucks are another story as is any body on frame vehicle.) Unibody cars use the glass to help hold the body in place.
