If you haven’t read a good justification for self-driving cars being service-based rather than ownership based, you have either read very little or chosen not to acknowledge the points you’ve read. I’m sorry that I don’t feel compelled to make an argument or point you in a specific direction, but it’s fairly hard to miss unless you’re trying to miss it, so this is more about you coming to grips with it on your own time. It’s not a matter of having to disprove the status quo — it’s that no one ever asked for the status quo’s proof, and now we are, and there’s no proof.

Your counterpoint is, while very narrow, one of the more valid outstanding questions about shared transportation — I’ve brought it up as a challenge numerous times before. That doesn’t mean the challenge will significantly prevent any progress otherwise. Here, again, one can find (or just look around and see) an overwhelming number of examples where *the problem with X* was either circumvented, solved in some alternative fashion, or outright forgotten due to the upside of a technology outweighing the hurdle of the challenge. Our entire species owes our success to solving problems in any way other than head-on.
