Nope, in most countries it's a requirement that you drive at a speed where you can stop in the length of the road where you have visability. It is plain common sense that to do otherwise is asking to have an accident, should anything be in your lane.
I suspect you two are also the sorts of idiots who don't leave enough distance between you and the car in front for an emergency stop, either - 2 second rule for dry conditions, and a bit more for wet or slippery conditions.

As for driving at night, that's when I prefer it, especially for trips, as traffic is light and you can make good progress - most of our roads are 2 lane (one each way) , twisting and unlit. When I was making regular 400 mile overnight runs between home and tech', my car had 80W low beams, which were also on with high beam (100W headlights plus 100W driving Super Oscar Cibies - 560W of overdriven QH - close to 2 million candlepower, IIRC) - at 14.3V they were enough to get flashed from a little over 5km distance. Low beam was good for a couple of hudred metres and would pick up street signs at least double that!

If you feel you must drive too fast in case you get tailgated shows two things, others are at least as stupid and that you should move to the slower lanes.

I have standard 55W headlamps and I drive at the speed limit of 70mph on motorways. Does that make me an idiot?
