Why is it illegal? Dangerous in an accident?
Yeah the first time I saw ploycarbonate was in metal work in grade 9 and the
teacher picked up a piece about the size of an A4 sheet of paper and there
about 5 guys standing right next to him and he goes "see this piece of
plastic?" and then he slammed it down on the corner of the metal work bench
and all 5 of us guys hit the deck wondering whether we would lose our
eyesight from flying shards of plastic, but no it stayed in one piece. He
said they kept getting broken into until they replaced the windows of the
workshops with it.
I'm fairly sure some CD-Rs are made out of something like it... when you
try and break them they just fold like the 'Lexan'.
