Long haul, local delivery, taxi, bus, you name a driving job and the ruling class will want to automate it.
Oh, absolutely. Most local delivery uses people who already work at the business, and delivery is just a small part of that person's job. So that impact is likely to be close to zero. But that still leaves probably probably around 5 to 10 million taxi drivers and probably three or four million truck drivers.
But taxi and truck drivers won't be replaced overnight. Most taxi drivers and many truck drivers own their own rigs, and although they may eventually replace themselves with robot rigs, they would continue to earn the revenue after doing so. They certainly have no incentive to fire themselves.
Ultimately, somebody has to own the rigs. There's nothing that necessarily requires that robotaxis be fleet vehicles owned by some big company like Uber, no matter how much companies like Uber might prefer it to be that way. Replacing all of those taxis with robot cars costs money, and Uber isn't capitalized that well. Uber's cash on hand wouldn't even be enough to replace all of the taxis in the United States. So while this may shift things around some, I wouldn't expect a taxipocalypse.
