Apologies if this has already been discussed, but I did a search and couldn't find a thread... On my run back home from work I seem to be seeing more people these days running white rear lights. I've seen several in the past couple of weeks. Is this some form of I'm-going-to-be-clever-and-get-attention and therefore be safer kind of thing? It seems massively dumb to me to deliberately try to "trick" other road users this way (as well as illegal, I guess.) Maybe I'm missing something....
