I feel like this problem is better in the UK than in North America.

For starters, there is higher market penetration for better headlight technology, particularly ADB (adaptive driving beam). North American road safety regulations have made it very difficult to get this technology into cars, whereas in Europe it is reasonably widespread. Even rental cars I have had in the UK have this technology- most recently a Mazda3 which had a very good implementation of it, I could drive through the countryside with high-beams on constantly, and you could see the car quickly dim the beam facing towards oncoming traffic if any came around a bend. These are not high-end cars; I have rented cars with a manual transmission and cloth seats yet better headlights than the fanciest S-class in North America.

There is also less variation in vehicle size, and better emphasis on road safety testing. In Canada I often encounter lifted pickup trucks, which changes the alignment of factory lighting, not to mention the lights on these are often aftermarket anyway and usually installed without any thought for alignment. British pickup trucks are rarer, smaller, and would fail their yearly MOT for having improper headlamp aim.

The problem with headlight brightness has mostly stemmed from cars having brighter headlights. I love technology, but if I had to choose between reducing light output, vs switching to harder-to repair, more expensive, less reliable computer-powered headlights, I'd prefer the former.

When I drive cars with old headlights, they are clearly inferior to the point of feeling nearly dangerous in some situations. I would also not call modern lights less reliable, although I am sure it is more expensive to repair modern lighting technology.

In a North American city where there is overhead lighting and the streets are a mile wide, sure, I could probably turn the lights off even and be totally fine.

In the middle of the British countryside on a single-track road that has hedges on either side, not enough space for cars in the oncoming direction to pass me, a 60mph speed limit, during a rainstorm? I want the nice lights.

Having excessively bright and blue headlights shined in your eyes harms your night vision and vision of anything not illuminated, which would exacerbate the seeming inferiority of other lights. In a narrow road during a rainstorm, driving speed should be significantly decreased to a level of safety - speed limits are not speed minimums.
