Not going to work. "One way mirrors" aren't -- they're just glass with a partially reflective metallic coating. Turn back 90% of the incident light and you've effectively got a window tinted about as much as a pair of mirrorshades (which isn't going to help with night driving). But the jackasses can just use a more powerful laser for their potentially-lethal lulz. Up the power tenfold and they can deliver the same amount of energy to the driver's eye.

The only really appropriate response is to enforce criminal sanctions against -- people who shine lasers into other peoples' eyes. Assault should cover it; no need for any new legislation. The issue is detection and enforcement.
