And since DRL systems usually use the high beams at half-brightness, you're

Doesn't anyone read the owner's manual any more? I'm sure it says you still
have to turn on the headlight switch at night, but there's thousands of cars
driving around with only half their lights on. I want a sign for my back window
that lights up and says "Please turn on ALL your lights!".
Though many confuse 'autolamps' with DRLs, there is no connection. I agree
that one should spend ten seconds learning the difference before taking a
new vehicle on the road.
Alas, few of us read manuals. Perhaps the software industry, which shoves a
new version down our throats every couple months and does not even provide
printed manuals anymore, is to blame. Of course, there is not much damage
one can do by driving a home computer without reading the manual...
Many countries, including Canada, require DRLs. One would expect that these
laws were enacted after some thought and are not the result of ignorance.
I believe that DRL's don't operate tail lights to avoid confusing them with
brake lights. As for semi-blinding oncoming traffic, at least in Fords, the
intensity is much less than half brightness. In DRL mode the high beams are
operated at 25% power, which probably translates to around 10% brightness
(at low power the filament is much less efficient). I frequently drive in
tunnels and can't even see my DRLs reflecting in the car ahead of me. I
suspect that those drivers who are blinding you simply turn their high beams
on by mistake - it's often hard to see the high beam indicator in daylight.
And by the way, I don't wish this experience on anyone, but after an
encounter on a mountain road with a distracted driver who veered into the
opposite lane, I became a believer in DRLs.
It will be hard to drive off at night with DRLs, thinking that these are
your regular lights, because your dashboard will be dark.
Also, Ford's DRLs don't turn on until you release the parking brake. Don't
know if GM vehicles follow the same logic.

Surely you know that there are many stupid laws on the books. The fact
that something was mandated by The Government doesn't necessarily mean
that it was intelligently considered -- or for that matter, done with the
average citizen's best interest in mind. Especially in Canada. ;-)
(Consider, for example, the mandatory center high-mounted brake light,
which history has now proven does *not* live up to its purpose of
reducing rear-end collisions.)
I, for one, find DRLs to be blinding on a sunny day, especially with a
fresh coat of snow on the ground. The amber ones I've seen on a few cars
aren't *too* bad, but there are times that I want to take a slingshot to
some of the clear/white ones.
I work for a 9-1-1 center, and I can assure you that people pull out in
front of cars with all their lights on at night (when cars with their
lights on are easiest to see) all the time. IMO, having DRLs on
motorcycles is not a bad idea, considering the bike's tiny silhouette,
but they are at best a nuisance on cars. --
Motorcycles currently use headlamps at all times. DRLs have been debated to
death in the NGs. There is no doubt DRLs can be an added safety item in
some conditions. As with the case with seat belts, there are situation were
they can do more harm than good. Test and practical experience has proven
that belt use prevents more injuries and death than they produce The
question is do the advantages of DRLs exceed the numerous problems THEY
present. I would suggest to anybody interested, on both sides of the
debate, that they do a search of the US Congressional Record for the reason
DRLs were NOT made mandatory in the US. Once you have the facts on both
sides of the argument you will be able to decide for yourself which opinion
is the most valid. Personally none of my vehicles are equipped with DRLs.
When I drive under conditions where I believe my vehicle needs to be more
visible, like driving with the sun to my back, I engage my headlamps for
