You are. Pretty much every other manufacturer offers adaptive cruise control, lane keeping, and the like. They're just honest about their capabilities.
Comparing Tesla's "full self driving" features to adaptive cruise control or lanekeeping is a very dishonest representation of the capabilities.
edit: I'm pretty anti-Tesla (strongly dislike the focus on the central screen and other driver-hostile 'features', don't think "full self driving" should be advertised as such, etc). But I still think their capabilities are significantly above the other car manufacturers enough that they shouldn't be directly compared in that way. But I guess readers like the fact that calling them "adaptive cruise control" and "active lanekeeping" is more accurate and much less bullshitty than Tesla.
