Response to Transport Canada posting re DRLs 8/11/00 3:25:31 PM

Refering to: Effectiveness of DRL in Canada
Transport Canada (TC) just doesn't get it. The only point they recognize is, "A very valid question has been raised in this forum regarding the measurement of 'only' DRL fitted vehicles ..." That's not the point. Let me make it crystal clear: the point is that DRLs in the US and Canada produce unacceptable levels of glare that is distracting and discomforting to other road users. Period. Do you understand? If not, please read the comments again. Unlike in Canada, US drivers are not going to put up, shut up, and give up when it comes to opposing this ill-conceived safety gimic. Stop trying to ram your ideas of safety via high glare DRLs down our throats.
Next, a look at your numbers. It should be noted that these are not independent numbers. They were compiled by TC for the purpose of justifying TC's mandate of DRLs. Government agencies and individuals in general do not like to be shown that their ideas may not work, so we have to seriously question how much of the data was "massaged" to give the desired results. Was the report externally reviewed by experts in safety and statistical analysis?
Regarding year-to-year comparisons, it is not clear whether the degradation of the older vehicles is taken into account. I.e., are older vehicles involved in more daytime collisions due to worn brakes, tires, and suspension? Also, the odds-ratio technique may be questionable since it compares the ratio of multi-vehicle to single-vehicle collisions in the daytime to the same ratio at night. It may provide a satisfactory measure of DRL effectiveness if the ratio of multi-vehicle to single-vehicle collisions were constant through daytime and nighttime. However, this is not necessarily the case, as the ratio rises and falls with changes in traffic density (Prower, 2000). Further, TC reports that a substantial decrease in multi-vehicle collisions in dusk/dawn conditions. What are the corresponding numbers in good daylight and why weren't these reported? Answer, because they did not look as dramatic, and this report is all about drama, isn't it?
And there are more questions. . . Has TC considered the long term effects of DRLs? Once everyone has them, does the supposed effect wear off? That is, why did TC notice a decrease in multi-vehicle collisions for one year old cars built the first year after the mandate, followed by less of a decrease for brand new cars built in the second year after the mandate?
Has road rage increased in Canada? Could increased driver anxiety be attributed to drivers facing bright lights at all times? What about collisions involving more than two vehicles? Have they increased or remained constant as was found in Sweden (Theeuwes and Riemersma, 1995)? Are motorcycle collisions on the rise? What about masking issues of other road users?
These are all questions that are unanswered by TC's report as well as NHTSA's preliminary assessment, indicating a heavy bias in favor of DRLs to support their own mistaken rulings.
It's pretty clear that NHTSA is in cahoots with TC. Did someone from NHTSA's Safety Performance Standards group invite TC to comment here? Will we need to make a FOIA request to find out?
