Uber is expanding its autonomous vehicle ambitions through a wide network of partnerships and investments. Over the past two years, the company has worked with more than 30 autonomous vehicle businesses, showing that its self-driving strategy goes well beyond a single in-house effort.

The company appears to be taking a global approach, teaming up with firms in different parts of the autonomous driving ecosystem. That suggests Uber is trying to build a broad foundation for future robotaxi and self-driving services by combining outside technology, regional expertise, and strategic capital.

Some of these relationships are simple partnerships, while others include direct investments. That mix indicates Uber is not just testing technology from the sidelines, but also placing financial bets on companies it sees as important to its long-term transportation plans.

Taken together, the growing list of autonomous vehicle partners highlights how Uber is positioning itself in a competitive self-driving market. Rather than relying on one path, the company is assembling a wide network of collaborators to strengthen its role in the future of autonomous mobility.
