As time goes on, Tesla's fiasco becomes more and more embarrassing. Waymos are all over the place in the cities they serve, doing pretty much what they're supposed to do. Nuro has some fully autonomous vehicles running around. Baidu's Apollo Go is deployed in 16 cities in China, although they use remote driving as a backup. Tesla, though, is still hyping a technology that seems to have maxed out years ago.
Which means if Tesla can really build that Cybercab - with an underpowered motor, small battery, plastic body panels, just cameras (which I think they promised to sell under $20k) - they'll be able to hit a business expense level and profitability that Waymo will only be able, in say, 10 years.
Even if you don't want to talk about non-existing hardware, a Model 3's manufacturing cost is surely much lower than a Waymo.
Once (if) they make self driving work at any point in time before Waymo gets to the same level of cost - they'll be the more profitable business.
Not only that, they'll be able to enter markets where the cost of Waymo and what you can charge for taxi rides is so far apart that it doesn't make sense for them - in this sense, they'll have a first mover advantage.
