       | themselves into thinking they're succeeding. At least for myself,
       | when I've got to deal with some kind of traffic control device
       | and optimize my driving around that (say a speed bump), it takes
       | my view/attention/focus away from looking for pedestrians
       | elsewhere.
       | 
       | There's also the general problem with stop signs that if you do
       | stop before the line as you're technically supposed to, then most
       | times you can't actually see oncoming vehicle traffic. So most
       | people stop over the line where they will be able to see, which
       | means they're not planning on stopping where pedestrians walk.
       | But fixing intersections is expensive meticulous work, while
       | fining drivers for dealing with what they've been given is
       | profitable.
       | 
       | If this were targeted at flagrant violations with warnings for a
       | percentile of marginal cases (ie getting people who don't stop at
       | all, and warning those who strain the idea of a rolling "stop"),
       | then I could see it. But as it's worded, and as speed/red light
       | cameras have been implemented, it just seems like another dynamic
       | of a dystopian hellhole.

         | In these cases there's usually some other violation that is
         | occurring, e.g., cars parked too close to the intersection, or
         | shrubbery not properly cut back. As you note, the result is
         | often they have to go beyond the stop sign. Even worse, I often
         | end up so far in the street that if there was a car that was
         | within its lane, but on the right-most side of it, they'd hit

           | I think the general problem is that the presence of the stop
           | sign and the 80-99% case (depending on the area/intersection)
           | being to only worry about cars creates a type of blindness to
           | pedestrians when they are there. Rather than these devices, I
           | would say it would be more effective to install flashing
           | lights on or around the stop sign, that turn on to signal a
           | pedestrian is crossing.

               | specifically to only draw attention when it's warranted,
               | to avoid that kind of fatigue. Like I think the
               | crosswalks with flashing yellow lights when pedestrians
               | are crossing are ridiculous overkill, but they don't add
               | to my oversignage fatigue because they only demand that
               | attention when the attention is needed.

           | 
           | E.g. in the Netherlands or Germany there's no need for 4-way
           | stops and such. If no other signage applies, then whoever is
           | on the "right" side has priority over the people on the
           | "left" side. And exceptions do apply, i.e. it's not "that
           | simple" either. It does depend on whether both roads are on
           | the same level or not. A road to your right that has a
           | sidewalk border stone running across it does _not_ give them
           | the right of way, while if the sidewalk border stops and both
           | roads intersect directly at the same level, then the road to
           | your right does have right of way.
           | 
           | So e.g. if you take a typical urban development with lots of
           | little streets and houses, where you'd see a lot of rolling
           | stops in America, nobody's gonna stop at every intersection,
           | rolling or not there. This does go as far as when cars from
           | all directions arrive at the same time, then nobody has
           | automatic right of way and one of them has to wave the person
           | to their right through and will be the last allowed to
           | proceed.

         | I do disagree about the rolling stop though. After drunk

         | 
         | Obviously there are degrees to rolling stops. one so slow that

           | especially if there are cars ahead of you or crossing.
           | There's no need to come to a dead stop (and for how long? One
           | second? Five? If you wait too long the driver on the cross

           | through a stop sign at a walking pace or slower that's not
           | materially more unsafe than coming to a dead stop, and
           | perhaps it is safer as it doesn't frustrate other drivers).

         | Actually zero all the time is impossible, of course. It's
         | possible that a 5mph collision with a frail pedestrian will
         | kill them. So Norway and Sweden sometimes have a fatality. But
