Unlike mountain lion attacks, dooring really is a danger. Most states don't record it as a car-bike collision, because they record those only if the car was moving. But Chicago did keep track, and found that something like 20% of car-bike crashes were doorings. Don't ride in the door zone. Just don't. Funny, I can't remember ever having problem with "door zones" and there was one area, actually a small bridge in a village I used to pass through where cars congregated. There was a bank just at the edge of the bridge which had ATM's there were always cars parked there. I never gave it much thought but what I think I did was to move out further into the road. I do remember having a couple of people open their door just a crack and peer out at me and then close the door and wait for me to pass. One thing that is difficult in discussing traffic in different countries is the different laws and customs. In Thailand, for example, if you were to open the door of your car into someone's path and they literally ripped your door off and punted it down the road that would be your fault and you would be liable for both repairs to your car, the "door ripper" and any damage the door did subsequent to being ripped off. But something that is happening in Bangkok at the moment might be of interest in the U.S. Bangkok is literally covered with surveillance cameras which are now being programmed to stop the rather reckless lane changing one sees in Bangkok. As of yesterday, in one day, they caught 750 vehicles making illegal lane changes and providing the program gets the go ahead traffic tickets will be mailed to the miscreants. The news article emphasized that each lane change is a separate offence so ten illegal lane changes equates to 10 tickets. Which, if the news article was accurate would equate to about 10,000 baht in fines. As a comparison, minimum wage here is 300 baht a day, at the moment. 10,000/300 = ~33 days of minimum wages. If the U.S. would install and program surveillance cameras to recognize bicycles and to identify those who break the various laws that control them it might put a large dent in the numbers of bicycle accidents. Be careful what you wish: https://futurism.com/facial-recognit...social-credit/ This will not end with lane changes and jaywalking. Nope. And don't buy a phone with facial recognition unlocking. |

Joerg talks with horror about his near misses, and about hearing from friends who heard from friends about other friends who nearly died. The usual nonsense because you don't read carefully. These were friends. People I hung out with all the time. And yes, they were hit by cars while cycling. Then there is the wife of a guy I regularly met on our dog walks. She was on a road bike and run over (literally) by a large pickup truck. It took years of medical attention and special training before she could even sit on a road bike again. Joerg, in one of your past horror story rants, you talked about all the cyclists killed "around here." I asked for links and got one article talking about a cyclist killed something like 50 miles away from you. Wrong again. I quoted numerous reports from the Sacramento Bee about cyclist deaths. All from the Sacramento region, Rancho Cordova and so on. It might surprise you but there are actually people from here who ride down there. I did yesterday. Some people do not just use their bicycles to go to the next grocery store. Folsom has only rare accident reports because drum roll they have a great bike path system. No cars, no being hit by cars. Simple. Cycling deaths are well recorded and documented, yet you couldn't provide evidence of your local killing fields. Wrong. I did. You just didn't seem to pay attention. ... I strongly suspect the same is true of the terrible number of near-deaths among cyclists you know. Or for that matter, of the mountain lion attacks barely avoided, the bike frames reduced to shrapnel by tire blowouts, the rides survived only by use of glaring lights... Believe what you want. I don't care. I do believe you drink a hell of a lot of beer, though. So manly! Got to run, have to bottle an IPA (no kidding). -- Regards, Joerg http://www.analogconsultants.com/ |

There are some that turn into flash mode when power comes on (without pressing the button) so with some simple electronics up front they could also be useful for dynamo-only situations. Though then they will go out when stopped which is not good. For front lights I'd like to see the same law for bicycles as we have in most states for motorcycles, daytime running lights are mandatory. Modulated or flashing is better, but even solid is okay. Oi. Where to begin. A flashing light in front is the most ****ing annoying thing ever on a bike (and I am speaking here from the perspective of the person *riding* the bike; it's even more annoying from the perspective of everyone else). For rear lights, most riders already use flashing rear lights. I never do. My taillight is always set to not flash when it's on. It's also annoying for those behind me. A solidly shining light is plenty visible daytime or at night. |

I can see DRLs and flashers in low light conditions, but actually requiring them for all conditions is dopey. I know you like to poke the ant-hill on this issues, so go for it, but equipment requirements will just turn into selective enforcement tools for cops who dislike certain riders. You're batteries run out, and some cop busts you because he doesn't like some ordinance you passed. We need to pass more laws to make everything safe for everybody. Actually I'm the only one on our council that's voted against some ridiculous new ordinances that try to do that. On one vote the City Clerk was so shocked that she reported the vote as unanimous and I had to interrupt her to correct her. Passing meaningless, unenforceable laws that are already duplicated at the state level is ridiculous. We have no real way to even prosecute violators of some ordinances because the county DA won't do it. OTOH, for some things, it's not that enforcement is expected, it's about getting people to understand what behavior is a good idea, and knowing that most people have the sense to do what the law says (seat belt laws, etc.). In my area, there's no need for laws regarding bicycle DRLs or rear flashers, since usage is already very high for transportational cycling. Some areas of the country could use this law. For example, in some counties in Ohio, such as Mahoning County, there appears to be a need for such a DRL law. Except that the collision rate there is zero. It's the last place that needs regulation because the drivers appear to be paying attention. That's another aspect of this law -- built-in comparative fault anytime some unlighted rider gets hit by a car, even if he or she is hit in broad daylight while wearing fluorescent clothing and pulling a calliope blaring The Liberty Bell march. It's negligence per se in most states and will go to the jury who may be disposed to hating bicyclists. You will be screwed if your batteries die, particular if you get hit by a car or look like an illegal alien or whatever else happens to be unpopular at the time. -- Jay Beattie. |

Today, I would say, that a large number, perhaps a majority of the street crime in Bangkok is "solved" by examining surveillance camera film. I've read that G.B, has more surveillance cameras installed then any other country in the world. But, if, as recently happened here, someone punches you in the mouth and steals your brand new iFone, do you care who's on Candid Camera? Nope, you just want your iFone back. -- Cheers, John B. |
