I have a bridge with a lexan ball ramp, do you? I've stuck a robot under said ramp while not getting anywhere near breaking anything, have you?
Did you fire bullets at it while it was under the ramp?

Quote:
We refer to it as bulletproof glass because that is the widely accepted term.
Just because you hear it on MythBusters or the CD community describes it as such does not mean it is a widely accepted term. It is not glass and it is not bulletproof. It is known in the military as transparent polycarbonate armor. Calling it bulletproof- you might as well say it is magic glass.

Quote:
Furthermore, 3/8" is legally bulletproof for small arms (paraphrasing modern marvels).
Legally bulletproof for small arms? What is the legal definition of a small firearm? According to whom is it legal? Please show me where the law states this. I know in Canada we have no such laws stating what is bulletproof and what isn't.

Keep in mind my job depends on building things that resist bullets among other fast moving projectiles...

Quote:
Are you saying there are no situations in which the 1/4" lexan ramp can comfortably hold something defined as a robot by the 2012 rules, with an appropriate safety factor and the risk of field damage minimized?
Not at all. I am not contesting its durability when tromped on by robots, I am sure it is plenty durable, although I wouldn't call it a bridge. I am contesting the statement that 1/4" lexan is bulletproof.
