So you mean like, "the whole point of self-driving taxis is that they are cheaper to run, ... and that's how they will compete?"

You're trying to convince yourself too hard that you disagree with the previous comment.

There will probably be a bit of both: using the margin to seriously undercut the taxis and ubers in order to drive them out, and then raise prices.

Why would you say that? I wasn’t trying that hard at all.

It just seemed that you were implying that they will be significantly cheaper for consumers which is not at all obvious at this point.
