How would you design that system?

I can't imagine a self-driving car request via an app could be accomplished without _someone_ knowing / tracking your travel patterns. You can't do cash transactions because that would be rife for smash-n-grabs from others.

With a regular taxi I just call from a phone in a hotel lobby and ask to be picked up a block or so from my location. No reason there can't be a dispatch service you can call for self-driving taxis too.

Crime happens, but that's why there's insurance. It's not like cab drivers don't get robbed too. It doesn't (and shouldn't) stop cash commerce.
