Hmm, you might be right about the problem being easier, or at least parts of it. Though, besides what others said about loudness and danger, I think the main point is cost. Even if they can be deployed earlier than fully autonomous cars, if they are too expensive (compared to alternatives) the adoption will be quite limited (and hence, not really working as "taxis" as I see it). Still cool though.
