Actually, it's the opposite.
Autopilot comes for free with Tesla.
I don't know of any car that gives Autopilot-like functionality for free. I'm certain BMW doesn't, I'm certain GM's Blue Cruise and Ford's Co-Pilot is a paid add on.
FSD provides functionality that isn't available on any car you can buy.
Specifically the $10k pays for:
- Navigate on Autopilot
- Auto Lane Change
- Autopark
- Summon
- Full Self-Driving Computer
- Traffic Light and Stop Sign Control
Those are FSD feature that are fully released.
The beta adds autosteer on city streets.
