I get really irritated when I'm sitting in slow moving traffic in the dark, and every time the queue is at a standstill, even if for a couple of minutes, I'm half blinded by the brake lights of the car in front.
Modern cars lights are way bigger and brighter than they used to be and most of them have a massive third brake light across the top of the rear window as well as the two usual lights. It is bloody uncomfortable and annoying to sit looking at them glaring garishly at me, and it obscures my view of the other surroundings.
When I learned to drive I was taught to always use my handbrake for any stop longer than a momentary (couple of seconds) pause. I still do this and I wish everyone else would too.
As you were.
