I find this with night cyclists.
There seems to be this idea that if you put a Star Wars directed energy weapon on the front of your bike you will be safer.
The trouble is, these ultra bight LEDs are (More or less) point sources. They are also not of a standard brightness.
The result, it is difficult to tell if that cyclist coming towards you is quarter of a mile away or right on top of you!
So is it safe to pull out of that side road or isnt it??
(I dont know what the final analysis was, but I have always suspected that something like this happened with
this incident. Night time, Wiggins probabally had an LED headlamp and since he was training, probabally riding a lot faster than most other road users are used too!)
