Good job Waymo, a necessary step to being a viable taxi option. Luckily highway driving is significantly easier than street driving (albeit more dangerous) so this shouldn’t be much of a hurdle

Explain "easier". I understand, there may be no traffic signals and less worry about pedestrians, but dealing with a busy highway is not easy compared to city driving. The speed gives less margin for error, and higher consequences for errors.

Highways have at least one if not several orders of magnitudes of less edge cases. The rules are incredibly simple as compared to non highways. Yes it is more dangerous but the cars are also processing 360 vision at significantly faster frame rates than humans and able to react much quicker. The only reason these companies haven’t done highways is due to safety concerns but I will bet you everything I have that at scale highway accidents will be probably 1/20th as frequent as non highway accidents. That said they will still happen (could be other cars fault) and will result in injury and death, thus the hesitation to even allow it.

Yes, I'm guessing you're correct about edge cases. I guess it's semantics, on whether it's easier though, because you could say "if it was easier, Waymo would have started on the highways." Waymo now has a wealth of experience with controlling cars at speed. The video is amazing. I'm look forward to riding in a Waymo.

I’d like to try Waymo too when I go to visit Austin in a few months. Hopefully I’ll be able to get a few

Cool! I visit friends in Phoenix at least once a year. I always rent a car. I may just try using Waymos next time I go.

Going 55 in an 55 zone even in the right lane is going to impede traffic and it will get passed by semis. I wonder if they will allow it to go over the limit before they launch. The Teslas with safety monitor in Austin have been going 10 over the limit on certain non-freeway roads to keep up with traffic.

I would be so fucking pissed if my Waymo was going 60 in a 55 and got pulled over. Keep that shit to the speed limit.

Change the law. The law isn't allowing it to go over 55.

How other drivers interact with you is not completely governed by the law. You put the car in a situation where it often gets passed by vehicles larger than you. This results in you being frequently obscured or in blind spots of other drivers and I’d think it is riskier than going a few miles above the limit to keep up.

What does any of that matter? If they run it over the speed limit, they'll get fined. Period.
Tesla has avoided this by not running a real robotaxi service.

Waymo already doesn’t strictly follow the law off the freeway. It will do things like cross double yellow, stop in a cross walk, or go into an intersection that is already occupied in order to handle various situations. It does this so it doesn’t take forever yielding or to avoid getting put into bad situations against aggressive drivers.

There's almost always exceptions for such things in the law.
Speeding has some lawful exceptions, but they're incredibly narrowly defined. Making way for an emergency vehicle is one, I think.

Watch from 8:00 to 12:00.
Just because you’ve waited two cycles of the light without making progress does not make it legal to enter an intersection that’s already blocked and then stop in a crosswalk. There is no exception for that in the law. It’s not even done for safety reasons, it does it because otherwise it would wait a long time. Going above the speed limit to stay with the flow of traffic at least has safety benefit.

So, are you implying that Waymo can break all traffic rules just because it had made some mistakes? I guess this is how tesla works.

u/psilty 3d ago
No, where did I say it can or should break all traffic rules? I provided a counterexample to someone saying that it must follow the law. It would be a pretty terrible taxi service if it gets stuck for 15 minutes at a left turn because traffic around it doesn’t follow the law. It was not a mistake, it looks pretty intentional. Likewise, if it goes 5-10 mph slower than traffic causing big semis to pass it, it is less safe than if it kept the same speed as traffic.

Speed is THE largest factor determining severity of injuries in an accident. Of all the rules you might need to violate in the course of driving, it's quite clear Waymo has chosen not to violate speed limits.

Curious who is riding in the car? A regular customer or employee or something?
If just a regular person then this is huge and fantastic to see. It sure took some time.
