It is a scam. "Full Self Driving" isn't even close to Level 3 autonomy or even Level 5.
Tesla got away with this deceptive advertising and scammed [0] their customers believing their vehicles would soon reach full self driving autonomy.
The only ones defending this are likely the ones that still haven't realized that they got scammed by Elon. Sorry that happened to you.

How is this false opinion so common? I use self-driving regularly it has always worked more or less flawlessly
