Going back to my early motorcycle days we were told to NEVER tint the helmet visor!
The reason being is that it would impede your ability to see a slick surface such as an oil patch on the road.
I use that information even today while driving my Tesla or my Goldwing!
Very dangerous to tint your front windshield. Don't do it! I believe it's also illegal.
The side windows and rear windows are fine.
There's just no reason at all to tint the front.
You're not impressing anybody!
