Yes, I know they've said that. I don't believe them. Or rather even if they do sell them I think it will be at a point where their robo taxi's are complete ubiquitous already.
I think you mean their stated intent is to eventually make this technology available to own (I haven’t watched the video you linked but I’m going to charitably assume they say what you’re asserting).
I, and many others, are past the point of trusting their words.
