Uber was working on self driving ten years ago. They had cars on the road loaded with cameras and sensors specifically to collect data. Then they negligently killed a woman crossing a street.
This isn't a pivot, this is them trying to sheepishly reenter the race they were dramatically ejected from.
The main reason Uber sold their self driving R&D unit was because they couldn't afford it. So they sold it to another company taking a 25% stake in Aurora and Uber CEO joined their board, the company is still operating automated trucking https://en.wikipedia.org/wiki/Aurora_Innovation?wprov=sfti1
They run trucks for Fedex in Texas and wants to offer an "Uber Freight network"
