Detecting Tailgaters With Lasers

stoolpigeon writes "Police in Arizona are using laser range finders to detect and ticket tailgaters. An officer can now measure not only the speed of passing vehicles but also how close they are to one another. The detectors described in the article are built by Laser Technology Inc., a company that provides lasers for traffic control, engineering, and even tactical/military solutions. The article mentions how tailgating is connected to many accidents and incidents of road rage; this observation fits my experience."

    Umm, no. Tailgaters are worse. There can be a smart speeder. There is no such thing as smart tailgater. Becauses, it is not speeding that causes accidents, it's the person speeding needs to take extra caution. It can be done, even if it usually is not. Tailgating in-and-of-itself is dangerous.

    Some of the comments there say that someone else will just pull ahead of you. Ahem, they will then get tickets. That's the point. Then they complain that they're close for a minute and get tickets, well, this complaint and the first complaint are opposites.

    I hope these tickets work. Next we can take on gawkers.

      What bothers me more than tailgaters is tailgaters who avoid EVERY OPPORTUNITY TO PASS YOU, even when there is another lane going the same direction. If they're tailgating when there's no chance to pass, okay, they're annoying me, but I at least understand their position. If they're tailgating me while passing up every opportunity to pass, WTF?

      And I hate to tell you this, but apart from emergencies and hazardous weather, if you can not safely drive faster than 35 in a 45, you should not be on the road. It's as simple as that. With the technology in modern vehicles, if you, presumably a fully functioning adult human being can not drive 45 in a 45, not only are you a nuissance, you are a risk to the lives of other drivers on the road.

      If you must drive, in the interests of safety I recommend you mark your car as a slow moving vehicle following the regulations in your jurisdication for the transportation of implements of hubandry.

If you feel that you can not safely operate a motor vehicle, there are public and private services available in most areas to help you meet your transportation needs.

      Bullshit. 45 is just a number they picked. Most speed limits in the US are not chosen to be the maximum safe speed. (And it should be obvious the anyone who's not a total moron that the maximum safe speed for a Corvette and a double-trailer semi are going to be VERY different numbers.)

      There are lots of reasons to drive less than the speed limit.

      Yes, and most of them mean either:
      A) You're not paying attention and are therefore dangerous.
      B) Your ability to drive is impaired and are therefore dangerous.


      Sure there are some exceptions, pulling a trailer up a big hill for example, but the vast majority of the time it's some jackass talking on their cellphone. Do everyone a favor, if you just *feel* like driving slow, pull over every once in a while and let that huge line of cars by you. (It's really the only safe way to get rid of tailgaters anyways.)

      Here's a story not unique and the poster above should have heard or seen several by now if they have grown up. I took a corner too fast on a mountain road under bad conditions while being tailgated - I should have known better and driven far less than the speed limit but I thought if I braked more the guy only two metres behind would slam into me. The fool behind me in that european sports car that could go quickly in those conditions didn't even stop to help or see if I was alive.

    My idea was a flashing neon sign that says, "back off!"

    Problem is, everybody thinks they're a perfect driver, and get very weird when anybody tries to tell them otherwise. Hence all the road rage incidents connected to tailgating.

    My strategy is to slow down, but subtly, so they don't register that I'm pissed at them. I don't even brake, I just don't push the accelerator as hard as a normally do. Invariably the tailgater gets impatient and passes, without registering any change in my driving.

    I'm going to be the contrarian here. Most tailgaters I see (including myself, of course) have legitimate gripes. If you have nobody in front of you and a queue of cars behind you, chances are you are going too slow!

    I always try to be aware of my surroundings, including looking in the rear-view mirror. If I'm in the left lane and there is someone approaching from the rear, it's easier and safer to reserve moral judgement about their character and do the smart thing--pull to the right at the earliest possible opportunity and let him overtake me. Why can't everyone manage to do that? See, when I happen to be the one in an unusual hurry, 9 times out of 10, the guy in front of me in the left lane is totally oblivious of my presence. To wake him up, I either have to drive dangerously close, pass on the right, or hit him with a few high-beam blasts. It's a no-win situation for both of us.

    Same with a single-lane road. If you simply must drive slow and enjoy the view, have the courtesy to pull to the shoulder when people approach who actually have a destination they are looking forward to reaching.

    Sure, there's the occasional idiot who gets in the left lane and tails everybody within inches, making them all pull over one by one, but these tailgaters are in the minority.

    Here's an idea, let the weavers assholes be themselves. Why would you purposely close the gap or actively prevent someone from getting in front of you? If you are driving too slow for them, let them be in front of you and eventually they will do it to someone else and be gone and you can go about your own business and not have to worry about them at all.
    I've often wondered why people play that gap closing game myself. If someone whats to weave in and out of traffic, let them go, as others have stated, in heavy traffic, it is not an effective means of making better progress anyway. You may feel they are being unsafe and maybe this is your chance to exercise your 4000LB weight around too as an equalizer? Closing a gap and disrupting the flow of a weavers is NOT safe either. If you want to play it safe, maintain your existing speed and gap and let the weaver go about his business. The weaver is not being as safe as he could be but closing the gap is not the safest thing you could do either.

    On that note... I live on a corner with a hidden intersection on a semi rural 2 lane state road. I see people pull out in front of cars all the time. One time a car pulled out in front of someone and that someone slammed on his brakes and laid on the horn until he came to a complete stop. After he came to a stop, he started yelling at the other person that pulled out in front of him as that person was driving by him in the other direction, the need for a complete stop was completely unnecessary. Hey, shit happens, get over it. Well now that he was at a complete stop and half way around a hidden corner and attempting to make his point known to a car that was no longer within hearing distance, he got rear ended by a third car coming up behind him on that hidden bend. Okay, technically he was not at fault because he got rear ended but his blatant actions had put himself in a very unsafe situation regardless of what the law states. I see a lot of people trying to be "safe" and educate other drivers on the road but in reality, they are being unsafe themselves. Just like the guy that hits his brakes when someone is tailing him. If you don't want to be tailed, move the hell over. I know a car is a big powerful glob of various metals and plastics but using that psychological power to force your driving ethics on others is NOT safe. Considering that the person is not going to change their habits because of your gap closing you have absolutely NOTHING to gain. Gee, I've been driving like a weaver for 20 years and today someone closed the gap on me. I learned a lesson and I am never going to be a weave again!

Besides, we really do see you blocking up traffic, and I'll bet that you've seen more than a few people pull out in front aggressively, it's not 'random' you've pissed them off for the last 5 miles. Classic deadly Road Rage is most often a response to poor/inconsiderate driving such as yours, the left hand lane is the 'passing lane' which means one should never 'keep pace' with a car to their right. Stacking up traffic behind you is a pile-up waiting to happen, sure you 'might' not be involved, but other drivers feel this danger, and will then act aggressively against you when they can. Some fearful people cocoon to threats, others swing out in rage. Ironically, it's likely you see it as 'they did not see your car, further reinforcing your 'rule', however it's a wonder you have gotten shot yet.

    Personally, I get a little 'spooked' when some does try to pace me, in particular the 'open' highway, if something like a deer runs into the road, it likely that we'll both try to avoid it by a combination of steering and breaking, and what are the chances that we'll do that at the same pace? I try my best to stay at a steady 10 mph over, moving over to the right to let faster drivers pass, and when I know that I won't be trapped in the right hand lane. Unlike others I really don't mind someone else passing me, but if I pass them again, I try not to let them ahead of me again.
