I think getting older has a lot to do with it - I used to love driving at night, "making progress" in various underpowered vehicles on back roads. Now with way more performance, even with better lights, and nowt coming the other way, I notice I'm a fair bit slower than i used to be.
Older eyes simply don't work as well.

From the original post if you think driving with modern headlights is bad it must be hell driving in bright daylight. I have an older model Berlingo and owners say how bad the headlights are but I find mine perfectly functional on dip and main.
