Self-Driving Ubers Appear in San Francisco

I can't wait to see these in Pittsburgh. If they can merge into traffic going into the Liberty Tunnels after a Pens game they can handle anything.

That being said, with the bulk of the reliable automation being on largely uninteresting well-labeled stretches of flat highway, doesn't it make sense to test these on long road-trips before we subject them to the volatile nature of city driving? I'd be interested in any insight into how engineers are tailoring these vehicles to their -at least by my standards- comparatively challenging urban testing grounds. Even if they've been trialed on road trips, this will be a very public and thus very decisive debut.
