I made the mistake of taking up my window tint guy's upsell in tinting my windshield (albeit lightly at 70%) -- my night vision is terrible enough, and it's enough to make me uncomfortable driving in the evenings. I know there've been some people who have encountered issues with windshield tint and the car's electronics, but that's mostly been on installation. Has anyone had their windshield tint removed, and is there anything to look out for?
