In the orignal post, I think he was talking about floated curved glass, this is used in telescope lenses and is usually purchased in small quantity, for an entire vehicle I feel it would be astronomically expensive and heavy. plexiglass or polycarbonate is lighter and has the advantage of being more easily formed. it has drawbacks in that it propagates cracks (the ones that look like spiderwebs) this is called crazing. and breaks down and browns in the UV of the sun and is extremely sensitive to being attacked by solvents such as acetone. I feel this can be gotten around by laminating it between tougher plastics or even doing a different configuration using a sandwich of glass and making the net shape out of a soccer ball type pattern. this may have a few interesting properties but in all likelyhood is a nightmare of complexity and then when you have your magnificent bubble top..how do you roll down the windows...open the doors/roof etc... it definitely comes with its own set of problems, legality though, I have seen cars that have such windows and apart from anecdotes, I have yet to see that this is actually illegal. but then again, I've never had a custom build need road certification. what about the aero-civic guy? isn't he on here? I know he used plexiglass for most of his modification
