Only cars made since late 2014: http://www.teslamotors.com/blog/dual-motor-model-s-and-autop... , so most current Tesla owners would have to upgrade.

This announcement is quite bubbly, IMO. Many luxury automakers have had the capability for "highway autonomy" in the way Tesla seem to describe for several years now: see this reckless Infiniti driver https://www.youtube.com/watch?v=zY_zqEmKV1k .

The "parking lot to parking lot" capability would be truly interesting (as city driving presents a lot of interesting problems that aren't just "follow lines and traffic") but as there's no announced timeline for it, there's no sign Tesla are actually ahead of the numerous other automakers working on the same capability.
