I'm just saying it isn't worth the trouble to try and educate or **** with every car on the road you feel has annoying lights. people are stupid and it'll not end well for anybody. blind them with your own brights until you pass and bust a move and drop them in traffic if they are behind you where someone else can deal with it. i refuse to drive all boxed in groups for any reason at any time of day and will be passing most traffic on the road or letting them pass so it just isn't that big a deal to me even tho i drive in dark to and from work most days. maybe tinting the window is for your own other reasons, blocking douches lights is just a side benefit. i like how it blocks the plastic panel destroying uv rays and helps my ac do better job, blocking some of the douche light levels is a bonus. just pickin my battles on the road. much more concerned with movement vs lighting, i want douches to just ******* pay attention and go or get the **** out the way or just sit there and watch me go by. 1 car cannot block all the lanes,lol......have fun widdit is how i cope. people get pissed when you are not held hostage to their driving habits and when you are amused and unaffected by their intestinal viewing habits. laugh at them. they get mad and sad instead of you. that's how I win.
