Disclaimer: I own Google stock simply by virtue of being invested in mutual and index funds, as are most people.
I'm (mostly) genuinely asking. I might have it confused with another company, and I have to admit I don't follow self-driving closely.
But also, Waymo was an acquisition (slightly arguable, since Google merged it with its own self-driving efforts, but the founding team was acquired). I asked for an example of an innovative product created from scratch at Google.
I don't think the fact that some of the first people on the team had worked together previously makes Waymo not "created at Google". The project they worked on before, the DARPA challenge, was not a commercial product, and at the time no company was seriously investing in self-driving cars as a viable technology. This isn't like YouTube, which was a well-known brand and viable business pre-acquisition. It was Google resources that made it possible to build the rest of the Waymo team, lobby governments to allow self-driving cars on the road, work with hardware manufacturers, and leverage the rest of Google's software stack, ML expertise, street view data, and datacenter capacity to build and train the driver.
