The less skill they have with statistics, the louder they screech that every study of an advance in safety is flawed and, anyhow, isn't necessary because 700 dead US cyclists every year is a small price to pay for the bees in their bonnets. That's bad enough, but worse is that they argue, either explicitly or by implication, that any cyclist who chooses to use advances in safety, for instance on the argument that the extra life saved may be his own, gives aid and comfort to the enemies of cycling by admitting that cycling is dangerous. Watch Krygowski screech "Danger! Danger!", without precisely specifying who or what he objects to because he knows he gets burned every time he tries his incompetent statistics on in public. As an example, the "cycling is safe crowd" consistently *overstated* the dangers in cycling by mishandling the national statistics, until I showed them that cycling is in fact much safer than they thought; not that they thanked me, as they won't thank you for resuscitating earlier generally accepted research. You need to tell them a hundred times, and it still won't get through their thick skulls, and another hundred times, and be prepared to do that every year that passes. The net effect isn't that they make fewer grossly untrue statements but that over time fewer people believe them and in the end the total number of people on that side of the fence become fewer and fewer and, ironically, as they ramp up the hysteria the harm they do becomes less and less.

Lazy "Crickets" Rolf is not telling. So I "consulted" with two experts after noticing DRL is not getting mentioned in all those lists of Volvo safety milestones. "People take a lot of voluntary steps to stay safe, says Saab safety expert Christer Nilsson, 'They don’t wait until a safety measure becomes law. For instance, when a 1960s Swedish study revealed that driving with headlights on during the day reduced the risk of head-on collisions, people started voluntarily driving with their headlights on during the day. In 1977 it became law, but people had already been doing it for years.'" https://www.drivingthenation.com/whats-sweden-got-to-do-with-it/ "In Sweden, the use of DRL has been compulsory for all motorized vehicles on all roads during the entire year since 1977. Although there are no legal requirements on how to switch on DRL, most modern cars are sold with an automatic ‘on’ switch." https://www.swov.nl/sites/default/files/publicaties/rapport/r-2003-28.pdf And it was indeed Kare Rumar who filled out that questionnai "DRL was used as one of the measures to reduce crash probability already during our switch over from left to right hand traffic 1967. In the following years DRL was used by the army, the railways and some companies in order to enhance road safety. Therefore the public was used to DRL and the campaigning was not as strong as would have been necessary without that history. Case closed unless someone (Emmanuel B.?) ambushes some long-retired Volvo engineer at the Volvo museum, and invests a can of domestically overtaxed beverage to find out the rest of the story. |

MOTORcyclists, what with their greater industrial and social organization have been seriously interested parties, willing to promote research on effectiveness.
And, they are concerned with masking effects of increasing prevalence of DRLs on automobiles. I will be unsurprised to be hit by an Audi driver distracted by his greater interest in the DLR pattern of a newer Audi than the one they are driving. Cynicism aside, I can’t compete for conspicuity with any motor vehicle after masking effects of their DRLs. https://www-esv.nhtsa.dot.gov/Procee.../05-0178-W.pdf |

Cynicism aside, I can’t compete for conspicuity with any motor vehicle after masking effects of their DRLs. https://www-esv.nhtsa.dot.gov/Procee.../05-0178-W.pdf Quite a few people seem to think that if something is good for a motorcyclist must be equally good for a bicyclist. A few of those people think such things should be mandatory for bicyclists. But bicycles and motorcycles have little in common other than wheel count. Regarding DRLs: What type of crash are people hoping to avoid? Motorcyclists use DRLs in hopes of preventing left cross crashes, where a motorist turns left directly into the path of a motorcycle he didn't see. These are huge danger problems for motorcyclists, causing over half of all car-motorcycle crashes. And at motorcycle speeds, it's easy for these crashes to be deadly. By contrast, that left cross scenario is only about 6% of car-bike crashes. https://www.fhwa.dot.gov/publication...e/96104/23.pdf And while these can be deadly, typically lower bicycling speeds increase the chance for the cyclist mitigating the crash by making a hard right turn, impacting the side of the car rather than the grill or hood. -- - Frank Krygowski |

Other 50% was a car pulling straight out in front of me from a side street. I've only gone down twice due to vehicles on the road. One was a left hook driver who claims he didn't realize how fast I was going. that still wasn't me hitting him or him hitting me. It was an endo due to hitting the front brake too hard on a fixed gear. the other was an actual collision but it was caused by a wrong direction riding bicyclist on a one way road who rode out onto the main street I was on but without looking or slowing. I was able to limp home after running into him but the frame and front fork of my bicycle would have cost more to repair than what the bicycle frame was worth. Had I been driving an electric car or scooter and hit him he most likely would have been seriously injured. I detest wrong direction and stop sign or red light running bicyclists who just blow through them at speed relying on others to either stop or get out of their way! Cheers |

Do we know that Scharfie is a soccer fan? I would've though his children were all grown up when the soccer craze hit the US, which was the introduction to soccer of most people over there. Whether Odense has a soccer team is something else I should know as my direct ancestor, Odin, the god of the Anglo-Saxons in Britain until they switched to Christianity, had his hall or seat there -- Odense is the modern version of Odin's See, in English Odin's Seat -- but as a retired rugby player I can't be bothered with soccer, or rugby for that matter, which I played only because it was compulsory at my house at my first university Daylight running lamps has seemed eminently reasonable to Volvo for two generations now.

But in the end that sort of marketing will give you a reputation as a panderer and do your shareholders income and stockholding harm.

No! That *can't* be the answer. Think of the [Andres] *children* Thanks, Tosspot. That Volvo, after it served on the school run, was a good fast cross-Europe touring car for a whole family, overnight from Cambridge to Juan-les-Pins -- after I positively located the rear axle and fitted a 5.7 litre Chevrolet V8 engine, and upgraded to "police pursuit" brakes; I'd ordered it new with the standard power steering deleted, so the steering was already suitable for what I intended. Since that big solid-looking estate weighed only 2800 pounds, with 300bhp and endless torque it was a fast car. I kept that car for 14 years, even though we only put about 3000m on it every year, until I went green in 1992 and sold all the cars as surplus to requirements. Still, reading Rolf's remark again, I wonder if Rolf actually knows whether daylight running lamps were forced on Volvo by the Swedish government or whether it was their own initiative, subsequently taken up by governments.
