This isn't a "9 out of 10 dentists recommend using our product" situation, and cellphone companies
have been sued for failing to deliver true unlimited plans.
It is being marketed as "Full Self Driving", and the CEO is publicly saying it is "in beta", "coming next year", and "just waiting for regulatory approval". In reality it needs constant driver supervision, is still primitive enough that it is directly linked to multiple fatalities, has been coming "next year" for over 6 years, and is clearly not even remotely finished. Customers have paid thousands of dollars for a feature they are not able to use, half a decade down the line. They may never be able to use it as advertised at all. The product as delivered is substantially different from anything the company says.
It's like saying your car can do 0 to 60 in less than ten seconds and then delivering a car without an engine - while putting a statement in the small writing that the car currently only reaches this in freefall from a mountain top, but pinky promise that they will install the engine in a few years.
