You've got to be joking, right? Tesla's Autopilot is utter crap that shits the bed with the first sign of dirt on any of the cameras, they opted out of using radars completely and they absolutely don't care about their customers.
Traffic Sign reading is laughably bad, the traffic sign detection is not working half the time and the auto pilot is still beta, because you can't depend on it at all.
Mazda's Systems are far from perfect, but for what they do, they are better than anything Tesla has. Mercedes and Audi have the "best", but Mazda isn't that far off, especially with the last updates it's gotten leaps better.
