It's exceedingly clear to me that they're talking about hardware that can support future capabilities -- additional features via software upgrades is something they talk about a lot. And they're very explicit about what their Autopilot system does and doesn't do on their site. There's basically no situation in which someone is buying a $70,000+ car without knowing how the Autopilot works.

It's really not that deceptive. People would have to be a lot dumber than they actually are to be confused about it.
