I would bet 85% odds that Tesla is eventually going to offer a refund to all current Model 3 owners who "pre-purchased" self driving. In fact, that's the event that is more likely to happen "coast to coast, this year".
Calling it now: There will be an "autopilot hardware v2." And Tesla will have to dig deep to pay back all that pre-purchased FSD cash, probably plus extra to stave off a class action lawsuit, which is its own risk.
I would love to see full self driving, but I don't trust that hardware. I would love to see Tesla succeed, but I fear that Musk himself will bring it down.
