I think the Goal would be Uber, but with a fleet of Apple Cars. I still dont see how selling and servicing Apple Cars would work for Apple if it is sold as an originally car. That large investment and sunk cost would be a good use for its Cash. ( And it would be part of their Services Revenue ) Apple also gets to trial and gather Data with their current Map Data Collection vehicle.
The problem is there is nothing, absolutely zero indication that we can crack Level 5 self driving within next 5 years. It is always easy to get the first 80%, the last 20%, the small and minor details will often take as long if not longer than the first 80%. We have just arrived at the 80% point, and there is always the illusion of we are close to Self Driving Goal. And we are not.
And apart from that there are no indication as to how Apple is competing with Batteries. Tesla as a car manufacture may be easy to replicate, ( only on a relative scale, it is actually difficult to make cars in mass quantities, especially with Apple that demands perfection. Unlike Tesla ) but Tesla Battery is at least 4 - 5 years ahead of everyone else from both technological and manufacturing. And no have seems to have shown a plausible plan of how Apple is going to tackle this.
