Yeah, I would say pretty much everybody is trying to do some form of "self-driving" to various degrees of success. They usually put cameras, radar and lidar on their vehicles, coupled with HD maps, and write software to tell the vehicles how to navigate and avoid hitting anything. And since a driver is in the vehicle to take over if necessary, the software does not need to be perfect. At this point, it's pretty easy to put a system together that can act like a self-driving system. Getting a self-driving system that is actually L4/5 reliable, that's the tough part.
