Have you ever noticed that most self-driving cars don't have any passengers?

"Deadheading" is an industry term for keeping driverless cars in constant motion, even when they have neither a passenger nor a destination. Waymo & Cruise rely on deadheading to avoid paying for parking.

Why pay the city for public parking when you can store your car on the road for free (as long as it's moving)?

Since I've started keeping track, I've noticed that over 90% of the self-driving cars I see are empty...

Tonight I spent one hour at the corner of Cesar Chavez & Guerrero St counting driverless cars.

Between 5-6pm, I counted 27 driverless cars, but only 1 appeared to have a passenger.

During rush hour in #SanFrancisco, 96% of the Waymos, Cruises, and Xoops on this busy street were empty!

edit: driverless cars can operate 24/7 in SF, but I've been informed that some are only taking passengers during certain hours (ie 9pm-5am). So the cars I saw today were probably not accepting any paid rides.

@docpop but they have to pay for fuel and wear out their parts, so why would that be a saving?

@docpop I thought they weren't allowed to have passengers during the daytime?
@seldo that could be true. I can’t say, but some do appear to humans in the back I assumed they were passengers, but I don’t know. I’d like to be corrected if that’s the case.
@docpop @seldo Yeah, most regular people can only (after signing up on a waitlist) use them from 9pm to 5am (I just got approved or whatever for that recently). There's a small number of testers who can use them outside of those hours.
@davewongillies @seldo thanks for that info. I’ve been looking for more information on this, but I’m struggling to find the hard details online. I found an article from last month saying the cars can be used as taxis 24/7, but I’m struggling to find the public information for which services are allowed to charge for rides and during what times.
@docpop @seldo A friend of mine is part of their testing program. He said that while Cruise does have the approval to run 24x7 for reasons he's not privy to they're not actually doing that yet

@docpop A first order estimate of the number of cars going to pick up people is the number of cars with passengers.

But even doubling the number of passenger-initiated relocations would still keep "productive" moves below 10%.

Of course, there are other reasons to continue driving besides the parking fees: 1. Acquiring more training data; 2. improving the statistics: Distance driven, distance without accident, …
But there should be disincentives of clogging the streets during rush hour.

@marcel @docpop are they EVs? How much are they contributing to pollution and climate change if they're continually moving?
@docpop we don't even need humans

@scott

What are the robots up to?

@docpop I haven't seen a single driverless car with any passengers, I didn't even realize they took passengers...

@docpop Cruise is only available to the general public 10 pm - 5 am. employees and friends and family can ride outside those hours but the map is still restricted so it’s not the whole city. Also not every car is assigned to being part of the taxi fleet. Some are still mapping and testing.

Waymo is still in beta. Last I heard 80,000 on the waitlist.

@eniatitova thanks! I've updated my post to include that info.

@docpop hello there, is there a chance you could talk to us about this 'deadheading' phenomenon on the #BBCWorldService radio, please?
@docpop what an alarmingly apropos metaphor for capitalism as a whole
@docpop this will kill cities. Drivers will start wrecking these just for jamming up traffic even more.
