They have delivered on the promise where the promise is in the fine print: the car is delivered with the hardware Tesla currently believes is required for Full Self Driving.

Until the software is up to the task, people who buy the FSD option get a bunch of convenience ADAS features like auto park, lane changes while on autopilot, taking exits or entry ramps while on auto pilot, navigating interchanges on autopilot, and stopping for traffic control.

The software currently delivers everything that the brochure says it can do, and Tesla is viably working towards the future product which can do the bits they want it to do, namely drive the car without supervision in most scenarios.
