"what if we installed a thing that was less functional and more expensive and required a lot more maintenance and also introduces new problems on top of solving no existing ones"
The only problem (one I REALLY have to nitpick on) that I could see this fixing is sometimes the windows are fogged up, making it hard to see what's inside.
yep, when I play hockey or go biking when the temps are low, glasses fog up easily from your breath. Just apply a very thin layer of dish soap, a small dab on both sides of the lenses then wipe off, just leaving a very thin layer that won't affect your vision.
