autowarefoundation/autoware ? reverse-engineered prompt

I want an open-source software platform that lets me set up a self-driving car system, using software that can handle things like knowing where the car is, spotting objects, planning routes, and controlling the vehicle, all designed for autonomous driving. It should be based on the Robot Operating System (ROS) and make it possible for researchers or companies to use and extend for their own vehicles. I don’t need anything fancy or extra—just the core functions needed to get an autonomous vehicle working, packaged so that people can install, experiment with, and build on it. Please make sure it’s structured to be easy for new users to get started, with references to documentation, and if there are missing details, you can look up the latest docs online.
