Brightness of lights

I was driving the rust ridden shopping trolley today in fairly good morning light and from behind I saw quite a bright flash that grabbed my attention, then noticed 4 cars back in my rear view the tell tale signature lights and xenons of a fuji probably prestige,

The lights were astoundingly bright compared with all the other cars in my rear view mirror!

I also like how, when the Evoque in your rear view mirror turns off and leaves you, the headlights wink at you. Apparently, this is a feature to make the indicator more visible, but it sure looks like the cars know each and are somehow communicating. Nothing else looks like an Evoque, even in the dark.

Audis also do this with their DRL's
