    I have beef against the new vehicles that you can't see the turn signals
    from every which way. If I see a vehicle stopped and can't see any signal I will
    assume they either don't know which way they are turning or are going straight.
    I knew the answer to retrofit current designs by putting signal up on the mirrors.
    One day I am crossing the street and see, i think a Toyota, that had the LED signals
    right where I would have put them. Thats what I'm talking about.

    You may want to consider limiting your drinking to the last thing you
    do in a given day.

    This is your entire probmlem. You have to drive as if they're out to get
    you, every time! It's called "defensive driving".

    But the socialists haven't taught anything real in the last couple of
    decades - just self-esteem: "Duh, I can't find Kansas on a map, but I
    feel REAL GOOD about myself, yup, yup, yup, yup."

    Feh. Learn to drive, otherwise you're a hazard to everyone else.

    Thanks,

    Turn signals should be ignored or at best be viewed with caution
    and suspicion, as they can be misleading, even if the driver had full
    intention of making the turn when turning on the signal. Several times
    I've seen someone activate a turn signal, slow down, and just about as
    the were going to turn, CHANGE THEIR MIND. I haven't seen that cause
    an accident yet, but it's been close. And said drivers likely had no
    clue why others blew their horns.

    Trusting a turn signal can kill a pedestrian.

    While riding motorcycles, I try to stay out of traffic. If that's
    not possible, I pay attention to what cars are doing and what they
    are able to do. I (should) never assume that the right-of-way will
    keep me from being killed.

    While in-line street skating, a geezer in a big car pulling out of a
    Wendy's parking lot stuck his head out the window and waved me on
    saying "Don't mind me!" I waited. So he tried to pull out onto the
    street, not realizing that his front tires were up against a curb.

    Besides intersections in general, perhaps the most hazardous
    situation for a pedestrian is when a car driver is looking left and
    turning right. When skating, I practice giving cars the
    right-of-way. A pedestrian pretending that he has the right of way
    is a big mistake IMO.

    Lack of driving skill, inattentiveness, and indecision is deadly.
    And then there is the woman pulling out onto a street with a cell
    phone in one hand and a cigarette in the other, I saw last week.

    While we're on a related subject, last night we went out to dinner in
    Providence, RI. As we're in a crosswalk and the car going northbound has
    stopped, had MA plates on it. The car going the other way, with RI
    plates didn't stop until I yelled out "WHAT THE ****!" and looked
    directly at the driver.

    That's the difference between MA and RI drivers. MA drivers will stop
    for someone in a crosswalk, RI drivers won't.

    I am a defensive driver. This has little to do about defensive driving.
    Its more about consideration. And the driver of that vehicle with less than perfect
    signaling might want to fix his problem. All the old vehicles had turn
    signals visable across the entire frontal area. For "styling" purposes, the
    car manufacturers are getting away with too much. I would have thought there
    was a spec for the turn signals, but its seems like its been changed or ignored.
    When that driver has his invisable turn signal on, he might think I can see it,
    and it might make my driving a little more unsafe and certainly his.

    I've driven in a number of different parts of the US and Canada and
    Europe over the years, and there are sections (e.g. Boston) where
    using your turn signal is a crime called "giving information to the
    enemy".

    Personally I liked the sequential turn signals on the Thunderbirds in
    the late 60's.

    I havn't sen anything like that today. There are some rear LED
    lamps that rotate, but it would seem like there would be more variety.
    I was mostly concerned with the FRONT turn signals here.

    I designed a chip (plus SCR's) to replace the motor/cam/switch
    arrangement in the original sequential turn signals in the '60's
    Birds.

    But I don't know of what you refer to as "new vehicles that you can't
    see the turn signals from every which way". All the new vehicles I
    know of have side (and mirror) lamps showing turns. Maybe you buy
    American-made junk ?:)

    Its very clear, for example

    these signal can be viewed from both left and right front sides, regardless of position.

    You can't The opposite side is hidden.

    Nothing about illegal. Its about comming to a stop at a three or four way intersection.
    Anybody can go any direction, except its nice to know who's going where.
    There must have been some kind of conclusion long ago, on where do
    you put turn signals since all vehicles had them in the front. I think
    it was a good idea. Addition of side markers was also a good idea
    as an additional benefit.


    greg
     
  12. Ah, but that assumes that you actually signal in the direction you
    intend to turn.

    I usually go by the rules of experiance. You can't always
    have a clear understanding of what to do. Its mostly
    by the wave of the hand, or who starts moving first, that
    sets the motion. Its clear to me, the first one to stop
    should be the first to go. Thats the only clear thing, and the
    guy on the right rule is not obeyed, except in boating.
    Regardless, if If someone is stopped, and I can't see
    any turn signal, they are either going straight, or deciding on something,
    and not necessarily going to make a turn.

    Are you worried about somebody going in your direction but in a lane
    to your right, and
    they're going to turn right but you can't see his signals? Don't see
    the problem.

    Or maybe you're worried about guys making left turns from the right
    lane, or right turns from the
    left lane? It worries me too, I've seen some scary moves over the
    years and thankfully
    nobody was killed (but there were some cars, trucks, SUV's totaled in
    the t-bones), but I don't
    think that turn signals address the drivers causing the problems.

  15. No, you need to learn to pay attention to what the hell you're doing.
    Turning off your brain, and depending on machines to protect you from
    your own negligence, is bad for the species.

    This is WAY too true. The one who has the right-of-way in any given
    situation is the one to whom it is yielded.

    Cheers!

  17. A. Put the passengers in Indy-grade cocoons.

    B. Don't stop in front of roads that traffic is coming out of.

    Or is it just that you love to say I'm wrong? ;-)

    Cheers!

  18. Well, I'm sorry if you're insulted, but it is a really abysmally stupid
    idea.

    What really needs to be done is to get rid of the all-or-nothing two and
    only two-party electoral system:

    For example, California has 55 electoral votes. If, say, 28 of them are
    for the pretty boy, and 27 of them are for the white-haired wrinkly guy,
    then when they report to the fed they report ALL 55 VOTES FOR THE PRETTY
    BOY. They ACTUALLY CHANGE YOUR VOTE!

    That's fundamentally wrong.

    Thanks,
    Rich

    European cars have 'side repeaters'. No excuse ever not to see them. But as usual, the
    USA's about 20 yrs behind.
