There is currently some kind of geomagnetic storm which is causing a lot of GPS tracks to be offset over the past few days. It's all over the running/cycling forums. Could be related, here's an example: https://old.reddit.com/r/Garmin/comments/vo17e2/the_magnetic...
This happens with a certain frequency in aviation
Relying purely on GPS (for self driving) won't work.

It couldn't possibly be GPS, right? Networks are unreliable, the cars must be able to reach a safe state if the network drops out. They appear to have stopped in the road. If these cars can't safely navigate their way to the side of the road using local sensors, they are wildly, hilariously unsuited for autonomous operation. > at least a dozen autonomous Chevrolet Bolts from GM Cruise Automation were spotted blocking…

Could be but a much more likely cause is a software update that went bad. Likely the cloud rained on them.
I don’t update any software I work on without canaries and a slow (order of days) roll-out, you think the bug manifested for a big chunk of the fleet?

Or I could be pessimistic about GPS -- these things are, albeit in limited numbers, on the road and actually being used by customers, right? I guess I'm surprised GPS is so reliable that this isn't a widespread, constant issue, if this is the normal "I lost GPS" behavior.
Computers are very far away from understanding where they are from context alone. Hell most humans don't know where they are. So if you have a short GPS outage they will be able to continue navigating due to other sensors, but the longer the GPS outage/issues persist the more unlikely it is that they still know where they are.
There should definitely be a safety to drive to the side of the road and wait though.

I rode in one recently. It was pretty smooth. An interesting thing: the car slowed to a stop in the middle of the street, and I couldn't immediately tell why. There was a row of parked cars on the roadside, and a person was walking around one of them to open her trunk. I guess the car was able to spot her in the dark and opted to pause. So we were stopped there. The woman threw her hands up as if to say, "whatcha loo…
Now let's imagine the same scene but with the car stopping right next to thugs breaking into another car :-D

Actually, autonomous driving stacks can get better doing millions of miles in simulation. The teen, not so much.
> Actually, autonomous driving stacks can get better doing millions of miles in simulation. The teen, not so much. Have they not already completed many millions of miles in simulation, back in 2018? To me, it looks like self-diving capabilities have reached a maxima. The resources poured into it have barely been needle movers in objective metrics.
If you thought drivers on the road are bad now, this is is a sneak peek of the dystopian future where other drivers on the road drive like they are a support ticket for Facebook or Google. If your situation isn’t covered by the preprogrammed logic, you’re out of luck with nobody to talk to. Self driving vehicles belong on rails.

As someone in the autonomous driving industry, maybe I can contribute a different perspective. I totally agree that better designed cities would be superior. When I took the initiative to participate in my local government, I was screamed and cursed at for the most trivial improvements imaginable, like a shared bike lane on a few miles of a particularly dangerous street. Multiply that by the opposition to actual impr…
Not totally on topic, but what's your take on being able to roll out autonomous vehicles in places with more "fluid" driving habits? I've driven in some crazy environments in the past, but I just came back from a very large country (let's call it an eighth of the world's population) where I can't imagine renting a car and driving there because of the near complete disregard they have for official traffic rules. Obvio…
I think the answer is going to be government rules because it's important that self-driving cars are predictable when there's no human driver you can have eye contact with in complex situations.

Given the list of things that could go horribly wrong with self driving vehicles, incidents like these are only a minor, harmless inconvenience. The more immediate concern is self driving vehicles that are clearly not ready to be on public roads being allowed to test (or not being pulled off the roads).
> incidents like these are only a minor, harmless inconvenience. Until there is a emergency vehicle thats unable to get through.

It's so tiresome that this (mostly false) story keeps coming up. The short version of the truth: The original owner did not buy AP. AP was enabled because of a bug. The dealer listed it as having AP included because, at the time, it was enabled. When ownership was transferred, the glitch was corrected, and AP was removed. The new owner bitched very loudly to the press, and Tesla restored AP to the car, for free, even…
From the users perspective, they purchased a car advertised with a feature. They could see it functioning. An over the air update removed the feature that they had "purchased" and tested. Yeah, I'd be mad as well. Good that Tesla resolved the problem but there is reason to be mad about a company retroactively removing features from a product.
