I'm on the road all day everyday, and people baffle me when it comes to lights. People driving around with high beams on, people driving around with no lights on, people whose brake lights are on all the time, the sheer amount of people that have that one bright headlight, either cos they've got the wrong bulb in it or because it's out of alignment/fitted wonky. And that's before you get to the new, super-fucking-bright LED headlights that blind you constantly.
Fucking cunts.
