As do I. It’s usually better if new products succeed rather than fail.
That said, I don’t think that robotaxis are going to be much of an economic success for Tesla or for Waymo or Zoox or any of the other competitors. I don’t think they’ll be able to improve much, if at all, on Uber’s economics.
Uber’s secret sauce - the magic behind the model - is that it monetizes existing but unused capital. You had all these cars, distributed throughout a metropolitan area, that were mostly being unused throughout the day. They already existed. All that needed to be done to get them generating revenue was for them to be put into service at times they were not.
That gives Uber some enormous advantages. There virtually are no marginal capital costs to have the fleet. The cars are already there. The parking is already there. People are already refueling and maintaining and cleaning the cars. Etc.
Moreover, the active fleet is always the right size (in mature metros), because cars can come in and out of service. If demand is high, you can pull more cars in; if demand is low, they just don’t run.
Waymo and Zoox and Tesla don’t have these advantages. They have capex to pay for cars to be in service. They have to pay for places for the cars to be stored. They have to pay for them to be cleaned and fueled (both overnight and during the day). And their fleet will often be mis-sized for the demand at any given time. During low points, they’ll have cars sitting idle on lots on their dime; during high points, they’ll be leaving money on the table because they don’t have enough cars.
I don’t think those costs will rise to the roughly $0.80 per mile that Uber drivers get paid to drive, as opposed to covering the operating costs of the vehicle. But they’re not nothing - probably about half of the savings from losing the driver will get eaten up by the capital costs of vehicles and storage. Then some of the rest will get eaten up by labor that Waymo and Zoox and Tesla have to provide that drivers provide as part of their service in Uber: cleaning the vehicles during the day, handling lost items, handling unusual driving circumstances (though that disappears as the AV driver gets better), etc.
Rough order of magnitude, I’d guess that a fully-functional Level 4 autonomous service can deliver rides for maybe 10-15% less than Uber. Around $2.50 to $3.00 per fare. That ain’t nothing - but it ain’t changing the world, either. Especially since the autonomous services will necessarily have longer wait times, particularly when most of the rides happen.
