Where to start for autonomous vehicle project

Hi

Looking for JEtson AGX as a start for development project (small in door autonomous drving vehicle) and looking for a quick start
1- is the Jetson AGX the right one?
2- Where and what sensors to look at, at the moment I’m not considering LiDAR, would cameras be sufficient?
3- How to lay out an architecture, is there a good forum to start from
