> Depreciation and utilization rates need to be incorporated.

That's tough to do, since we don't know either one. I suspect there's also a (perhaps incorrect) assumption that an unused auto-car will be "just sitting there" rather than moving, in which case utilization is, effectively, 100%.

That's not possible with a human driver in at least the case of a long one-way trip. However, with auto-cars, this could end up merely increasing the capital cost at the expense of unpaid/empty trip cost.

The extra cost is something I mentioned in my latency/jitter comment, wrt cheaper parking.

> $5.38/hr which is not all that far from what Uber drivers net

I didn't check your arithmetic, but, if so, it's is quite far from the fair/livable wage of $15/hr that at least I've been assuming for this conversation.

The fact that rideshare services are currently, effectively, paying much less is certainly an indication that even that may not be enough to lure people away from ownership.

Utilization rate means percentage of time that is billed to a customer, I believe/presume. Whether a car is moving is not the same thing. The issue is whether it is on the clock or not, and given that computers already are used to match passengers and route cars, I'm not clear on why we would expect a drastic increase. Currently, we see 50-60%. Even a perfect routing algorithm can't make it 100%, because there are only so many customers, so things like how many cars there are per customer matter. If you reduce the cars per customer, service suffers. If you increase the number, utilization falls.

It depends on what the denominator is.

If it's only the time between when a driver/auto-car "accepts" the ride and the end of the ride, there's little reason [1] to expect a drastic increase.

However, if the denominator is the total time the driver is "on duty", which is, I believe, what is generally used to calculate rideshare drivers' effective hourly compensation, then my original point stands. That is, an auto-car can be "on duty" even while just sitting in storage.

The current algorithm also doesn't tell rideshare drivers where to be while on duty, only routing them once a ride is requested. In the auto-car scenario, the computer has complete control, so a predictive algorithm could increase utilization, even if the denominator is time-in-motion.

Whether any increase would be drastic is debatable, but there's opportunity for something.

[1] Currently, the computer routing algorithm has an incentive to optimize for time at the expense of distance (since it's the driver who bears the expense of the unbilled distance, AFAIK). In the case of an auto-car, that perverse incentive would be absent, but I don't expect the difference to be huge.

"That is, an auto-car can be "on duty" even while just sitting in storage."

If you consider the robot to "work" for more hours than a human, that's great, but due to the lower average revenue, it needs to be cheaper in order to be competitive with humans. There's no way to move your self-driving car to the opposite side of the world for the night.

"Whether any increase would be drastic is debatable, but there's opportunity for something."

If self-driving cars are cheaper, it seems like that would lead to more of them driving longer hours than humans, which would lower the utilization rather than increase it.

It's unclear to me, but this may be tautological, or at least reversible (by being cheaper to be competitive, it reduces revenue). Perhaps I'm missing your point?

> There's no way to move your self-driving car to the opposite side of the world for the night.

Ah, but that's moot. Unlike with a human driver, an auto-car doesn't need to be moved to the opposite side of the world (or an approximation, like Sacramento from SF) for the night.

> If self-driving cars are cheaper, it seems like that would lead to more of them driving longer hours than humans, which would lower the utilization rather than increase it.

You're still confusing "driving" (in motion) with "on duty".

Also, even if an auto-car is cheaper while driving, that doesn't matter if the different parties are bearing the cost of off-meter driving. In the auto-car case, it's the vendor (e.g. Uber), so there's a strong incentive to maximize utilization. In the human case, it's the driver, so the vendor has no such incentive (nor even the ability during "on duty" but not driving-for-that-vendor times).
