I don't think that it is up to the states. Windshield systems are now
considered part of the restraint system and as such are covered by NHTSA
vehicle safety regulations. The state rules that I found on-line
simply point back to 49 CFR 571.5 -- the actual text of which I cannot
coax out of Google. In any case, it looks like AS-1 lamanated safety
glazing for motor vehicles is currently the only legal windshield for
highway use.

The "not-wiper safe" part will be a show-stopper. The government is
never going to allow a windshield that interfers with driver vision.
