Daytime Running Lights changed ???

I don't care!
I'm going to go pick the lint off my socks, it's more interesting

There was press report last year that EU road casualties were little different from countries using DRL's than those not using DRL's. EU road safety data for 1989 - 1995 shows that Sweden is not as safe as the UK despite the use of DRL?s.

(source - The Times 03/06/98)
Fatalities per million miles
Britain
64
Sweden
65

In Canada there was a 12% reduction in accidents when DRL's were introduced, but during the same period there was a similar decrease in accidents the USA which did not widely use DRL's at that time.

I understand in Australia that DRL's have been tried but abandoned due to no perceivable benefits.

One concern has been that DRLs on motorcycles are being masked by cars with DRLs. Motorcycles become less noticeable, and then involved in more collisions, many of them fatal. Motorcycle fatalities have shot up from 22.66 fatalities per million miles in 1994 to 38.38 in 2003. DRLs first widespread installation on GM cars was in 1995. We may be killing motorcyclists with automobile DRLs.

And does that have anything to do with the number of motorcycles on the road increasing between 1994 and 2003, or no?

First we are killing the planet with DRLs, now we are killing motorcyclists. They are probably responsible for aids, the holocaust and the existence of drugs too, right?

If you read the post a little more carefully before shooting off at the keyboard, you'll notice the data was normalized per million miles.

No, I noticed that. But there are still changes between the times that you conveniently left out to help your cause, whatever that may be. Not the first time you left out or exaggerated facts, and you just want unbiased reports.

You also skipped the last part of my last post. So, now that our DRLs are responsible for killing the planet, accounting for 1% of the nations gas consumption everyday, and are responsible for the slaughtering of poor motorcyclists everyday. What's next on your list? Really, what happened between you and DRLs? My guess is, DRLs killed your father, raped your mother and molested you. So, out with it already.

Maybe you'll have less resistance on this topic elsewhere, like maybe the prius forums or another suv forum that needs a new troll.

No, it's actually per 100 million miles. Just checked the NHTSA website.

AND, motorcycle accidents actually DROPPED when DRLs started being used (95-98).

1994 22.66
1995 22.73
1996 21.78
1997 20.99
1998 22.31
1999 23.46
2000 27.67
2001 33.17
2002 34.23
2003 38.93

Besides, none of this matters. I'm guessing that there are so many statistical variables, there there's no way with any level of confidence (at least a 95% confidence interval) to prove anything one way or the other. A common statistical fallacy is to assume since the average number changes that it's the result of something - without a real statistical analysis, there's no way to tell.

An example of a real statistical analysis is this:

This from a 2000 NHTSA report on driving distractions:

Driving Distractions NHTSA Report

"Surprisingly, large numbers of comments posted in these areas addressed the use of Daytime Running Lamps (DRLs). Nearly all were negative comments relating to the practice. DRLs were perceived to needlessly draw attention away from the road, reduce the conspicuity of emergency vehicles and motorcycles, contribute to glare and driver fatigue, and cause other drivers to adapt their behavior in manners that may not be safe. The main concern appeared to be with the use of excessively bright lights. Calls for limits in brightness as well as research to document the effect of DRLs on crashes and the visibility of emergency vehicles were made by many participants."

I stand corrected on the 100 million miles. I am not sure why you think the day GM puts its first DRL cars on the road, that the fatality rate should shoot up. You are just looking at noise. There is no doubt that the rate is skyrocketing starting in the year 2000. DRLs the cause? Maybe. DRLs on vehicles aren't going to help motorcyclists, especially if cars keep using headlamp based DRLs, instead of the turn signal type.

Michael

Screw the DRL's, they should at least be driver-selectable.

And motorcyclists know that the recent rise in death rates won't be cured by DRLs alone. No doubt DRLs help motorcycles stand out, just as they help with auto visibility on country roads etc. But I've driven in Canada in the sea of DRLs and most of the time it adds no value. Don't trust the auto manufacturers alone and their spiel on safety. Remember how slow GM was to adopt ABS. And how come vehicle stability systems are not standard on all their SUVs if they are so concerned with safety? DRLs are cheap. Dollars and cents are more important, business is business.

Is this the new highway safety forum?
