The real term is “marketing puffery.” It’s a fun, legally specific way to describe a company bullshitting to hype its product.
Puffery is like saying this is the best canned chili ever made. Selling a can of chili but never actually giving the chili just an empty can is fraud.
A robotaxi rollout where each car needs a safety driver is fraud.
The Robotaxi service might be puffery, selling "full self driving" is just fraud.
