Tesla's FSD problem isn't the technology, it's the positioning. It's genuinely good at what it does but selling it as "Full Self-Driving" set an expectation it can't meet. If they had framed it as the best safety feature, always aware co-driver watching out for you, people would trust it far more and adoption would be much higher.
Good point, full self driving probably felt like marketing win back then... but now it is a liability.
Rebranding now would just highlight all missed promises
