Good assumption, but nothing to do with it. Daytime lights on bikes have only proven good. Makes them more visible so you don't pull out in front of them and cause an accident. I've seen it work. Same for cars, especially the ones colored the same as the pavement, including bumpers. Seen that too.
As I said, they are standard on U.S./Canada GM vehicles - as far as I know. DRL's are the law in Canada. Easier to standardize production. Congress should give Canada the "facts" about DRL's. Include that crap free with the "Waterboarding Manual." Congress conclude? Might be a good idea. Probably got paid by some anti-DRL greenie wackos via lobbyists. DRL's burning use some gas, adding to global warming. Are you part of that crowd? Don't worry about it. You can bypass DRL's in the U.S. and do your part to reduce global warming. Turn down the heat in the house just to be sure. I don't care much about DRL's one way or another, except for arguing More concerned that my toaster doesn't zap me when I stick a fork in there. So I don't.
