AFAIK, pretty much everyone is. That's really been the big shift over the past few years that's allowed for fairly impressive autopilot levels without AIs having to "understand" and parse the world to nearly the degree people do. Presumably vehicles connected to the system will be able to contribute to updates but maintaining current, high resolution maps across a wide area will certainly be a challenge. It's not unreasonable to think that the government could play some role as well as it does for marine navigation.
