Nobody outside of tech understands it this way. "Full Self-Driving Beta" is a marketing stunt that borders on fraud. These cars can't drive themselves for shit, they're not even in beta.
You own/owned a Tesla with FSD Beta, right? You have driven it extensively to see and understand its capabilities and how it's improved, right? I've driven FSD Beta now for more than a year. Based on my experience you have no clue about which are speaking.
