Are you familiar with the outrage that NSA spying of people's communication caused? What makes you think that after all the data breaches and privacy violations, people will be okay with someone recording them in a car? The recordings are permanent, unlike the taxi driver's vision. Plus, the point of the self-driving car is to free people up to do other things. It's like your own room. The ability to lock the car down is frightening, because as it was stated, in a centralized system it could be used by government in any way they want, the same thing they're doing with data - they said they're gonna collect just metadata, but the truth is much more disturbing.

Wouldn't people rather be in their own semi self-driving car, where they are not recorded and can go anywhere they want(including very long distances or bumpy terrains), plus they could take control of the car anytime they wanted? That would be a more reasonable option for many, not a taxi that you have no control over and where you're recorded like a rat in a laboratory.
