I’ve often thought that we could polarise the headlight glass one way, and then windscreen glass the other. The glare off the road would still hit you but the lights themselves would be much darker, but still enough for you to see they’re there. The day-runners in the corners could still be unpolarised so you’d still see the vehicle. It’d be a bit more expensive and require collaboration between the manufacturers which are probably two large reasons why it would never happen.

I’m sure solving this problem isn’t beyond the wit of humanity, but is beyond the expense threshold that the oligarchs will tolerate from their dividends.
