There's a lot of competition in the autonomous driving space: Uber, Delphi, Cruise, Waymo, Ford, Volvo, Zoox, Varden Labs, Auro Robotics, Navya, Nuro.ai, Baidu, Tesla, Faraday Future, Mercedes, Nissan, Toyota, Yutong, and there are others (including some in stealth mode that would rather not be mentioned).

Udacity also has a course just for making a self-driving car, and you get to use a real car.
