The marketing is weird. They mix up current capabilities and future aspirations deliberately.
For instance, here:
> The system is designed to be able to conduct short and long distance trips with no action required by the person in the driver’s seat.
They actually mean that the system is designed such that "in the future" it will be able to do this. The previous sentence is "All new Tesla cars have the hardware needed in the future for full self-driving in almost all circumstances", and you're supposed to carry that context forward into the following sentence.
Another aspiration, which if you weren't reading carefully you might assume was a present capability:
> All you will need to do is get in and tell your car where to go. If you don’t say anything, your car will look at your calendar and take you there as the assumed destination. Your Tesla will figure out the optimal route, navigating urban streets, complex intersections and freeways.
It's intentionally misleading.

PS. Yes, there are caveats: "Current Autopilot features require active driver supervision and do not make the vehicle autonomous". That doesn't make the rest of the marketing copy clear.
