Now look here. The other day I was driving (with lights off) my Micra K-11 (good car btw, had one since 2000) where trees made it a bit dark. Dude stepped into the road forcing me to brake, and I'm sure he didn't see me because he was looking at his smart phone.
The point is, he may have seen a car that had lights on. And the point is also, why should drivers have to put lights on so people can read phones and not bother looking where they're going?
