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.

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 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.

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.
