No, Tesla does something much, much more complex. They build an entire 3D representation of the world and do path planning inside that virtual model. Check out the videos from the last Tesla AI day. They are creating a voxel representation of the world, doing object classification and loading objects into the world, doing monte carlo tree search path planning in the virtual world, etc.
