The polarization is built into the display screen. (Translated: There is no reasonable way to rotate it)
Opinion: Polarized glasses are bad for driving. (Ignoring the fact that almost every car has some LCD screen these days, causing the problems noted above) Polarized glasses are great when you are on the water (boating, skiing, etc) but when on the road, they make it harder to see wet areas on the road. That means that you might hit a big puddle or spill without realizing you were about to. Neutral Gray lenses are better. (Note: this comes from driving experience on the racetrack, where missing a fluid spill could have tragic consequences.)
Sorry if I'm...

I own no garage queens. If it's in my driveway, it's been ridden hard and put away wet. ...and now, with a light crust of Maine road salt.
