That’s such a show of confidence! It’s an entirely different driving world over there. Particularly in terms of what is expected outside of what is mandated.
Looking forward to trying it.
In my experience the cars are highly regulated and very predictable on the main roads. Marked out lanes, low speed limits, many red lights.
But pedestrians and bikes are everywhere, and they don't always obey the rules. I wonder how well collision detection handles sharing lanes with bikes without suddenly braking in the middle of the road.
I was in a Waymo last week in San Francisco that had a bicyclist cut in front of us, no hard breaking or jerk just a gradual decrease in speed. I would've hit the break relatively fast myself but Waymo handled it without issue in a very smooth way.
I don't know how it'll handle significantly more pedestrians, but I assume that they're confident enough in the models and have run enough simulations to expand to Tokyo.
I bike in SF regularly and I actually cut in front of Waymos intentionally since I know they will slow down gracefully vs regular drivers who might not see me for a number of reasons or trigger road rage. Several months ago a Waymo would over correct but now they're so good at anticipating where I'm heading.
In San Francisco, pedestrians and bikes can appear anywhere around your car, at any speed in any direction. Including wearing all black, no light and taking 2 steps forward then turning around and taking 2 more steps forward (repeat but vary everything randomly). Or doing lasso circles with something heavy at the end of a rope in the middle of the street (last weekend). Just because this is not 100% of the time is not a license to run over ANY of them.
This is a kind of environment that human drivers are NOT made for. All the more not while clicking around on their Uber app or changing the music track or trying to read street signs or understand a Nissan dashboard map. In San Francisco, computers with multiple sensors have a gross advantage over humans.
I live in rural Japan, and in my experience, drivers are also crazy:
* They stop on the side of roads and streets whenever they feel like it without worrying about blocking the traffic.
* They don't turn the lights on no matter how bad the weather is. Super fun to be in the middle of a snow storm and people are driving white cars with the lights off.
* Whenever someone wants to turn right at an intersection, the cars behind will pass it on the left, without worrying if someone is coming the opposite direction, which is really dangerous. I am not sure about the Japanese law, but in my home country (Spain) that is highly illegal.
* Many people watch TV or anime while driving. I even saw one guy reading a book while driving, somehow holding it open over the driving wheel.
Add to this the awful state of most streets and roads, and I can see more accidents here in one year that I saw in 33 years in Spain.
How would passing on the left would risk a collision with a car coming from an opposite direction? The opposite lane is on the right hand side (in Japan)?
I assume they mean: Given turning/waiting car A, passing car B that is going straight and car C coming from right going straight. Car B likely has right of the way as they are going straight and they are on the left from viewpoint of car C, but car C may not see behind car A (like due to it being truck for example). Both B & C might think they have right of the way. B due to fact they should normally only need to avoid people coming from left and he can see there is no one there, C due to fact he entered intersection when he only saw A who is waiting to turn. I don't know Japan law so I don't know actually has right of the way here (in Finland A would actually have right of the way in mirrored situation as you always need to yield those coming from right in equal intersection, even if they are turning left).
Yes, it is a question of visibility. You have two cars coming from opposite directions, both want to turn right (Japan drives on the left), and both think they can do it safely, but all of sudden another car pops from behind.
I have seen many near accidents due to this. That's why such a maneuver is forbidden in many countries.
True. It doesn't help that most streets don't have sidewalks and you are forced to walk on the road. And even when there are sidewalks, people ignore them...
Oh, I mean — that's a thing even in the densest parts of Tokyo, people (and not just tourists!) just have no concept of moving aside to not block the flow, frequently walk like 3/4-abreast and block the entire width of the stairs/sidewalk ;P
