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.
