No need to give up. Just acknowledge that is a hard problem whose success date is notably indeterminate. Then stubbornly refuse to talk about future features and only talk about one's already shipping today. If the future is going to arrive so soon, why bother to break in advance? Let everyone be amazed when it does arrive. I love the autopilot feature, but the cars are still great without it. Tesla can be very successful and sell a lot of cars without any more self driving features.
