Well, I guess there are a lot more candidates. One likely to be replaced are actors in movies and TV. It wont be long and they can be replaced by CGI, and only the voices will be spoken by real people - but for much less pay.

And I agree, that drivers are very much in danger to be replaced. That would mean a enormous amount of people loosing their jobs.
All this will require a new social-economical system, in which the increased profit from automated work is shared with the then unemployed people. If not, there will be major unrest.
