Waymo as a system has crossed the threshold where I trust them more than average driver, but all this hardware is relatively new, well maintained, and their software is closely tied to it.
I’m way less confident of self driving in the hands of the general public when differed maintenance often results in people and even companies driving with squealing breaks and balding tires etc.
I am also not looking forward to the system transitioning from "big experiment, burn money to make it good" to "established business unit, tweak it to death for incrementally more money / personal promotion." We're still in the honeymoon period and I very much expect to hate Waymo in 10 or 15 years when they reach a steady state.
What levers are there, really? Waymo has a monopoly and it seems like they will for a while, so they have a lot of power, but all I really see them doing is making it expensive. Anything that makes the experience worse takes away from their ability to take market share away from Uber/Lyft.
Self-driving vehicles need aircraft-type maintenance. Yet there's nothing like the FAA to enforce a minimum equipment list, maintenance intervals, or signoffs by approved mechanics.
Is there a scratch or chip in the scanner dome? Are both the primary and backup steering actuators working? Is there any damage to the vehicle fender sensors? Is dispatch allowed with some redundant components not working? If so, for how long?
Here's the FAA's Minimum Equipment List for single-engine aircraft.[1] For each item, you can see if it has to be working to take off, and, if not, how long is allowed to fix it.
There's nothing like that for self-driving land vehicles.
What's the fleet going to look like at 8 years of wear and tear?
> Self-driving vehicles need aircraft-type maintenance.
That's a hyperbolic false equivalence.
Aircraft typically carry hundreds of people and can crash to the ground. As long as a self-driving car can detect when it is degraded, it can just stop with the blinkers on. Usually with 0 - 2 people inside.
The question is how broken can a car be when dispatched. What's the safe floor? See the other article today about a Tesla getting into an accident because of undetected sensor degradation.
> Aircraft typically carry hundreds of people and can crash to the ground.
Cars are more numerous and could spontaneously either plow into pedestrians, or rear-end someone, causing chain damage and, quite often, a spillage of toxic chemicals (e.g., a cistern carrying acid/fuel/pesticide).
Plus, you have a problem of hostile actors having easier access to cars compared to planes.
Waymo's software has crossed multiple generations of sensors and vehicles over almost two decades. It does not seem to be tightly coupled to a particular device.
Not tightly coupled in obvious ways, but as I understand it they aren’t putting it on pickup trucks, convertibles, or anything toeing a boat etc. Their vehicles don’t have aftermarket suspension systems dramatically changing handling characteristics, or turned one into a stretched limo etc.
Which means the software can safely assume the vehicle will behave within a relatively narrow operating range.
I don't think the vehicle performance really matters in the typical case. They're using like 20% of what the vehicle "can" do. They're probably hedging against the long tail of variance on the road somehow. Kinda like how private people can tow whatever the f they want with their pickups but in a work setting you need to keep it fairly stupid proof.
I suppose owners will be motivated to have the thing do the driving (and so seek defeat devices and such), but at least the software can have "do nothing" as a safety mode if it manages to detect that the vehicle is not configured as expected.
And maybe the software can be designed to be coupled to a vehicle dynamics model that can be updated.
The new (as of now than a year ago) Waymo cars still had human safety drivers last I saw one (a month or two ago). I also don't see them taking customers. So they do seem to slow roll hardware rollouts.
The way I see it, self-driving cars have the potential to deliver us from the burden of ownership altogether--maintenance, insurance, liability, parking, and all the rest. This hinges on availability, quality of service, pricing, and a rather large shift in the culture around cars and driving but I have hope that we can get there with time.
It's not obvious that will exist in the near future, anyway. Waymo aren't planning on selling their cars, and the economics and liability structure of self-driving strongly bias towards just running a taxi service.
We're not even a decade beyond some poorly conceived software crashing two otherwise functional aircraft into the ground and now it's going to save us all...
