There is that nothing infuriates me more than the high intensity rear lights.
These so called drivers cannot discern between fog and mist. I've said it before, we haven't had a good pea souper to enable us to utilise these lights in well over 30 years. If say it's an early Autumn morning with a morning mist they think "Oh it's foggy" and switch on the H. I. R. lights and away they go, this is why I dreaded driving in the winter months. Apart from the fact they are totally unnecessary they don't bother turning them off till Spring, I've lost count of the number of times I've followed vehicles with those lights burning my corneas, and it's no good flashing or gesticulating because they'll either totally ignore you or, if it's a pig ignorant know all, they'll get out and threaten you, they actually don't understand what the problem is when the problem is bad driving.
There should be a way where the H.I.R. lights can be automatically cancelled out in good weather, after all there's plenty of computerised equipment on board nowadays, like telling you there's low pressure in a particular tyre or the outside temperature so it wouldn't be a massive task, or they can even be cancelled out when the ignition is switched off.
Or better still if the car drivers just concentrated on what they are doing.....that would help.
