My car has the auto full beam thingy, but I don't think that is the problem, if the car approaching is dazzling me I flash them (ooh er missus!) to remind them and more often than not they then flash me back. Quite often the oncoming car will be coming over the brow of a hill as I approach, nothing you can do about, but I do think it's the modern headlights unfortunately, My headlights are ridiculously bright, great for seeing the road ahead, but without the auto dim they would be dangerous for oncoming drivers. Most cars on the road don't have a lot of the fancy pants tech available nowadays, so I fear we will just have wait until the vast majority of cars have the modern headlight systems and hope there are not too many accidents as a result.
Driving has been my bread and butter for the last 40 odd years but I am thankful I rarely need to drive at night nowadays.
