> Once a driver knows the car next to them isn't driven by a person it changes their behaviour.
If the car next to me isn't driven by a person, but is bristling with high resolution cameras that will immediately upload footage of my face to the authorities if I collide with it, I would indeed change my behavior.
I wear a helmet cam, and yes, as an individual it's basically impossible to get traction, even when you have a clear plate and face shot. But when the self-driving car company has thousands or millions of these incidents on record, they'll quickly find themselves wielding enormous power.
They'll be able to correlate across time and space, similar to how phones running Google Maps are reporting their position and velocity to create up to the minute traffic overlays. They'll be able to approach politicians and police forces with a message like "hey, want to get serious about safety? These are the top one hundred drivers in your area who need to be taken off the road now— click through to our portal to find dozens and dozens of videos of each one speeding, weaving, failing to yield, running stop signs, etc."
Each individual incident may be hard to prosecute, but when you have all of them in a bundle, a few a week for months at a time, it'll become impossible not to act on it. When crashes happen, they'll be able to shame the jurisdiction after the fact by publishing dumps of the incidents leading up to it that were not acted on.
Heh, imagine "vigilante" network justice. Oh, hey, you messed with our cars one too many times. We'll arrange for some cars to line up in front of you and drive 25.
They would simply report their customers just as well. Covering them up is a liability, they would probably have another way to tell anyways. I got an automated parking fine from a shared car a few weeks ago - it's real.
Eventually, money. You have to imagine that info about dangerous drivers would be tremendously valuable to insurance companies as well, if it could be shown to predict crashes.
In my experience, I have never been surprised by overly cautious drivers, only drivers who have an excess of confidence. How do you define 'excess caution'?
For the most part I don't really disagree with you, but there are ways drivers could behave unpredictably out of what might be called an excess of caution. For example, my wife just yesterday told me about something that happened to her that day. She was waiting to turn right from a side street, behind another car also turning right. The first car started their turn, she pulled up, checked that there was ample room, and so started to turn in behind them. Then the car in front slammed on their brakes, stopping partway into the lane. It seems they did this because there was a car approaching in the distance on the main street.
The thing is, that car was far enough away that both cars could have easily turned in front with room to spare. My wife had seen it before starting her turn, and realized there was plenty of time. In fact, after a few seconds, the driver in front of my wife realized just how much time they had, and finally made the turn, still before this other car arrived. Because my wife is an attentive driver this wasn't a problem, but you could certainly see a driver in her position starting to make the turn while looking to the left, and rear-ending the car that suddenly stops for no apparent reason. Of course they would be at fault for doing so, but the first driver's excess of caution, if you want to call it that, would also be a contributing factor.
Been surprised plenty by “overly cautious” drivers, mostly having to do with slowing down or stopping unexpectedly.
Folks that hit the brakes crossing a green light. Braking well before the off ramp so they are going 40 on the highway. Slowing down while merging.
The worst ones are those that are scared to go but decide too late. Like stopping in the middle of the intersection while turning left because there is a car coming from the distance but late enough they end up blocking the left lane going straight.
As a frequent pedestrian in Seattle, overly cautious/"courteous" drivers are a big nuance. Particularly drivers who are over-eager to stop at crosswalks, sometimes parking in the middle of the intersection to wait for the cross walk on the other side. Some drivers around here have a habit of stopping prematurely too, waiting for me to cross before I've even gotten to the intersection.
Sometimes it gets truly absurd. Once I was standing on the sidewalk at an intersection waiting for an Uber when a driver stopped at a green light and started honking at me, furious when I refused to cross the road.
In Seattle all unmarked intersections are considered pedestrian right-of-ways, by law. There have been campaigns to promote this. Ten to twenty years ago it was not uncommon for pedestrians to throw tantrums and shame drivers for not stopping them, usually in Fremont and Capitol Hill. That may explain some of the behavior; possibly the drivers you encountered were native Seattlites with intersection PTSD.
But I generally agree with you. it’s a often egregious and can be extremely dangerous for both the pedestrian and other vehicles when a lone driver stops unexpectedly on a >2 lane road.
In some states, you can and will be ticketed if you don't stop whenever someone steps off the curb. I seem to remember hearing or reading that is the case in Massachusetts, so you may see drivers from out of state being very cautious even elsewhere.
Also, the other day, I was making a left from a one-way street, from the left side of it, and someone tried to drive around me on the shoulder to the left, because they were unaware I was waiting for a jogger pushing a stroller to cross in front of me.
I almost got run over today on Capitol Hill because of this. A driver in one direction was so insistent that I cross in front of them that I failed to be sufficiently attentive about the other direction and almost got hit.
In Portland, OR we have 4-way intersections where the stop signs alternate every 2 blocks. Drivers still tend to stop at every intersection, even when they have no stop sign.
Ha, I don't come to a complete stop, but I'm guilty of slowing down at the intersections without stop signs because I've experienced enough instances of cross traffic blowing through their stop signs. In the city I think it would probably be better if all intersections were four-ways.
If the car next to me isn't driven by a person, but is bristling with high resolution cameras that will immediately upload footage of my face to the authorities if I collide with it, I would indeed change my behavior.
