Serious crash rates are a hockey stick pattern. 20% of the drivers cause 80% of the crashes, to a rough approximation. For the worst 20% of drivers, the Waymo is almost certainly better already.

Honestly, at this point I am more interested in whether they can operate their service profitably and affordably, because they are clearly nailing the technical side.

For example data from a 100 driver study, see table 2.11, p. 29. https://rosap.ntl.bts.gov/view/dot/37370 Roughly the same number of drivers had 0 or 1 near-crashes as had 13-50+. One of the drivers had 56 near crashes and 4 actual crashes in less than 20K miles! So the average isn't that helpful here.

I saw a transit enthusiast YouTube video try out Waymo from the most distant part of the network to fisherman’s wharf in SF and it cost twice as much as an Uber while having a longer wait time for a car.

It also couldn’t operate on the highway so the transit time was nearly double.

One shouldn’t underestimate how economical real human operators are. It’s not like Uber drivers make a ton of money. Uber drivers often have zero capital expense since they are driving vehicles they already own. Waymo can’t share the business expense of their vehicles with their employees and have them drive them home and to the grocery store.

I’m sure it’ll improve but this tells me that Waymo’s price per vehicle including all the R&D expenses must be astronomical. They are burning $2 billion a year at the current rate even though they have revenue service.

Plus, they actually have a lot of human operators to correct issues and talk to police and things like that. Last number I found on that was over one person per vehicle but I’m not sure if anyone knows for sure.

The wait times have gotten better, they're getting freeway approval shortly which will be nice, the price is still at a premium (but worth it imo). I only take Waymo in SF now.

The only time I take Uber in the bay area is to the airport (and when they approve Waymo for SFO I won't take Uber then either).

I saw a transit enthusiast YouTube video try out Waymo from the most distant part of the network to fisherman’s wharf in SF and it cost twice as much as an Uber, had a longer wait time for a car, and cost about double.

That's literally an edge case. For shorter trips, I've found it to be slightly cheaper (especially factoring in the lack of tips) with maybe a slightly longer wait.

I generally find that Waymos are cheaper than Uber/Lyft including tip.

I’ve also seen that, although Uber and Lyft peak times seem correlated to each other, they seem uncorrelated to Waymo peak activity. But this might be stabilizing as Waymo ridership increases.

Both the longer wait time and the double price can likely be explained by the lack of highway.

Highway is coming.

And scale will make it cheaper. It's only cheaper than Uber sometimes currently. That will change.

My experience using Waymos in SF is that they are a little less expensive than an Uber. The other advantage is that you aren't stuck with a driver who hits on you or wants to share his opinions on the best way to slaughter goats.

Waymo rides are also potentially slower because they strictly follow speed limits. Not really problematic in downtown SF but it’ll be interesting to see how it’ll be received by riders when they expand to highway driving where most people generally expect to drive over the speed limit.

On most trips people do speeding saves an irrelevant amount of time. If somehow you encounter zero traffic from Palo Alto to SF and you go 15mph over the limit the whole way it makes the trip about 5 minutes shorter.

You have about 50% more KE at 80mph as you do at 65mph btw, if you find yourself needing to dissipate that energy rapidly.

Sure, there’s the math, but there’s also the human nature part of it. If you’re sitting in the right lane doing the speed limit, watching dozens of cars consistently zip past, it feels like you’re “falling behind” all of that traffic. I wonder how that will be received by the riding public.

I don't really find this to be the case at all. I've had Waymo for ~2 years now (since the private program), and I've never noticed it being quicker or cheaper than an Uber. I have several hundred rides; I prefer the service - but I've never once told people it's cheaper or faster.

Currently, on Wednesday March 26th at 8:34 a ride from Bar Part Time in the Mission to Verjus in North Beach is $21.17 with a estimated 8 minute pickup time. The same ride on UberX has an estimated 2 minute pickup time at a cost of $15.34. I could see it being cheaper if you top 20% - but I don't tip nearly that high on Uber rides.

I will admit that I could possibly be self-selecting to peak times as I own a car in the city, so I only use ride share in the evenings; so it may very well be the case that the price/wait is more competitive at off-peak hours.

Furthermore, it's quite surprising to me that it seems that the human labor cost doesn't affect the price at all. The only price controls seems to be demand and the latent demand is enough to create a price floor where there is always a human that is willing to drive. It also seems like plain old logistics and traffic will prevent Waymo from providing enough supply to offer dirt cheap rides. The fact that a ride that would have cost me $5 in 2016 is almost 4x as much with "magic self driving technology" is not something I could have told my 2016 self.

This comparison doesn’t work.

Not all Waymo riders actually want the premium cars and we can’t assume that’s why they are choosing Waymo.

We have to assume that some and perhaps most riders would prefer to pay less to ride in a cheaper car but are mainly choosing Waymo because its autonomous (cool factor, the no-human factor).

Also, California mandates autonomous vehicles be fully electric by 2030. So Waymo literally has to be driving some kind of EV to comply very soon.

Jaguar’s I-pace was a poor-selling EV SUV from a struggling company with a lot of leftover inventory, so it’s almost a guarantee that Waymo got a great fleet deal on them.

I mean yeah, right now they've hit the point of being quite safe, but they're not necessarily as fast as human drivers. They'll keep making incremental progress and will get there eventually, probably.

You are also comparing Way-mo to UberX when it is more comparable to Uber comfort, but that’s often only a few dollars difference. Really, Waymo needs to come to Seattle, our uber costs are sky high and it would be easy to actually be cheaper than most uber rides here when it’s already $40 to go a short distance.

The cars are comfortable, even if they aren’t popular. If I had to choose between a beat up Prius uber-X or a Jaguar for a few dollars more, I’m definitely choosing the latter. I had a Mercedes (older cheaper model with mechanical issues) Uber-X fall apart on my ride in Orange County last month (my son and I were dumped near a nice mall at least), also I bet the Waymo doesn’t smell like cigarette smoke.

I've used Waymo in both LA and SF and lived it. However, wait times in LA varied hugely. Downtown LA one evening was over twenty minutes and a few hours later less than five. I wonder if they just don't have enough vehicles there and because it's such sprawl it can easily happen that no car is nearby.

It's likely often repeated because if you try driving 55 in a 55mph zone where people are driving between 62-70, it'sterrifying, it feels like you're stopped. Whether the stat is true or not remains to be seen, but intuitively, it makes a lot of sense. Sure, your risk of rear ending someone at that point is probably negligible, but the odds of being rear ended? Hard to say

> One shouldn’t underestimate how economical real human operators are

That's such a silly statement. One shouldn’t underestimate how UNeconomical real humans are.

In the past 12,000 years, human efficiency has improved, maybe, 10x. In the past 100 years, technological efficiency has improved, maybe, 1,000,000x.

Any tiny technological improvement can be instantly replicated and scaled. Meanwhile, every individual human needs to be re-trained and re-grown. They're extremely temperamental, with expensive upkeep, very short lifespans and even shorter productive lifespans.

In fact, humans have improved so little, that every time, they scoff at the new technology and say it will never take off, and they're still doing it 12,000 years later, right now, right above this post.

For the opposite experience, take a taxi in a low- or maybe middle-income country.

Fascinatingly, every argument you make is wrong.

> it cost twice as much as an Uber

Surely incidental since the typical price per ride is about the same. Generally though, the relationship between the cost to operate a service profitably and the price presented to the user is very complex, so just because the price happens to be x right now doesn't tell you much. For example, something like 30% of the price of an iPhone is markup.

> while having a longer wait time for a car

Obviously incidental?

> It also couldn’t operate on the highway so the transit time was nearly double.

Obviously easily fixable?

> One shouldn’t underestimate how economical real human operators are.

There's nothing to underestimate, human drivers don't scale the way software drivers do. It doesn't matter how little humans cost, they are competing with software that can be copied for free.

> Waymo can’t share the business expense of their vehicles with their employees

They can share parking space, cleaning services, maintenance, parts for repair, etc.

> I’m sure it’ll improve but this tells me that Waymo’s price per vehicle including all the R&D expenses must be astronomical.

Obviously, they're in the development phase. None of this matters long term.

"The stock market went up 2% yesterday so it will go up 2% today too and every day after that."

> Plus, they actually have a lot of human operators to correct issues and talk to police and things like that.

Said operators are shared between all vehicles and their number will go down over time as the driving software improves.

---

To sum up, every single part of what Waymo is trying to do scales. Every problem you've mentioned is either incidental or a one-off cost long term.

In the UK the speed limit for goods vehicles is 10 mph below the limit for cars on motorways so there are plenty of vehicles driving below the limit.

The real risk is the opposite, cars bunched together at the same speed. This is where pileups occur, somebody at the front does something stupid and the people at the back end up colliding.

Worth noting how much the quality of each tier of Uber has degraded as well. In 2025, Uber Black car/driver quality is like Uber-X of 2019. Not unusual to get in an Uber Black with blown out shocks, smelling of cigarettes and streetcart food. Reminds me of yellow cab days.

The misconception here is that technology just magically runs on its own.

No, it’s created by and maintained by humans. You’re shifting the cost of a driver to software engineers, data analysis, people mapping out roads, etc.

This is why Uber doesn’t make any money, despite being more expensive for the customer as compared to traditional taxi services. Coordinating Ubers across the country costs a lot of servers and a lot of engineers. Sure, the system is automatic - maintaining it isn’t.

So you end up with a lose-lose-lose scenario. The ride is more expensive for the customer. The driver makes less money. And Uber bleeds hundreds of millions a year.

Technology is neat, yes, but often we don’t stop and think “wait… does this make sense?”

We don’t know if autonomous cars make any economic sense. They could end up not. It doesn’t help that 99% of tech companies in the transportation space are just making trains with extra steps. Like, guys - have we even done feasibility analysis?

It’s great that you and the other contrarians in this thread value that, but my point is that the general consumer likely overwhelmingly chooses to pick whatever is cheapest save for specialized selections like XL or pet.

I think the best evidence of that is how uber/lyft has to use grey-ish patterns to get you to choose upmarket options. They don’t list the fares sorted by price or even list the options in a consistent order, they will strongly suggest upsells like comfort or black or whatever tier they think gives the best chance of convincing you to pay more than the bare minimum.

They also upsell faster pickup which I have to think is a way better value proposition than sitting in a nicer car temporarily.

The number one tech bro blind spot is the assumption that everything in the physical world scales with software and that every business and type of cost benefits greatly from economies of scale and the removal of human labor.

There are a great number of examples where that’s not true. Cookie store chains like Crumbl are a really good example. All the economies of scale stuff with them backfires. The product is too low price and too simple to make in batches, so the businesses with the best margins are ones that avoid traditional brick and mortar rent and don’t hire employees.

In the same way, an uber or taxi’s labor cost seems like it’s a huge scaling problem that needs to be resolved but really think about the costs involved with creating that scale to replace them.

Let’s not forget that at Waymo they still need a human to clean, fix, and charge/gas up, interact with customers and police, resolve driving edge cases, etc, all costs that a human driver essentially includes with their pay and does for “free.” Then you’ve got car storage and the capital expense of the vehicle that the uber driver heavily subsidizes and splits between business and personal use.

Basically, Waymo is looking to compete using their very complex and sophisticated solution in a market where its competitors are hiring lowest bidder temporary contractors.

Will it change?

Uber drivers are already paid low wages and any price competition can lower their wages further.

Waymo has to pay for things that “come with” uber drivers: the cars, storage for the cars, employees to clean and maintain the cars, extra infrastructure to support the self driving cars like cellular data for each car, data centers, engineers, customer service to interact with police and resolve edge cases (will never go away). Waymo also has to pay all these people healthcare benefits and pay W2 payroll, not a thing for Uber.

Waymo is like a professional moving company competing on price with an army of lowest bidder independent contractors who already have a beat up graffiti van.
