I also hope Musk reconsiders his strategy of not making much cheaper EVs "because everyone will pay to be driven by an autonomous vehicle soon".
I think he's way overestimating how soon that will happen. I don't think most people, even in the U.S., where a "Tesla Network" may actually be viable, let alone in the rest of the world, will do that by 2025, if not 2030. That leaves a lot of wasted opportunities for Tesla to become a "market leader" in EVs - or rather to maintain its EV leadership in the market.
By 2025, there will definitely be EVs from Renault and others that cost less than $20,000 and have 200-mile ranges. At half the price of a Model 3, those cars are going to gain a lot of market share, fast, even if Tesla's numbers continue to grow as well.
I know Musk has already mentioned that Model Y will be cheaper, but we don't know just how much cheaper. Hopefully, it will be like $25,000. That would be a nice price-point for an EV by 2020. But I think Tesla needs to go down to $15,000 or at least 18,000 by 2025, as well, even if for that price point and by that moment in time, those cars can't be "Level 5" - although if Model 3 will have that hardware, I think so will the $15,000-18,000 car by 2025 (it will probably need to be more like 2023, and announced in 2021, though, as a lot of EVs will start to come out in 2021-2022).
