If anyone, it could well be Apple that can catch up with Tesla's self-driving capabilities.
When it comes to Tesla, they might be sitting on better technology than it might seem at first glance.
Although I'm not sure they'll manage in Europe, pedestrians and cyclists are more common and have better rights. Does Tesla get enough non-visual wavelength information from front sides, to avoid pedestrians and wild animals? Tesla's self-driving story could be cut short in Europe the first time the car kills a cyclist crossing the road in low visibility conditions, like during heavy snowfall.
Can Tesla manage in low angle sunshine and snow or dirt on the cameras? Humans can shift their viewpoint, but cameras can't. This could be particularly difficult in North Europe.
Some Asian markets like India and Vietnam could be difficult for them because of chaotic traffic systems.
Addendum: If played "right", self-driving can be $100B+ business. I'd expect true poker hands to be only shown once time is right and legislation allows it.
