What is the relationship between FSD and autopilot? Is it included in all cars and just disabled or is it separate software sent to cars with FSD vs. not.
Will FSD improvements affect autopilot at all or are they not making any improvements to autopilot?
The way I understand it is that FSD is the highest form of autopilot. All Tesla cars have the ability to do it, but it's disabled. If you bought FSD and have signed up for the FSD beta, then a separate software version is sent to your car. As far as I know only some changes for FSD improve the basic autopilot. In the future, I'm thinking they may replace the older autopilot code with the newer FSD code, but without all the features of FSD.
All Tesla cars come with basic autopilot to keep the car centered between lanes with adaptive cruise control.
You can pay for enhanced autopilot which includes these features:
- Navigate on Autopilot
- Auto Lane Change
- Autopark
- Summon
- Smart Summon
If you pay for FSD, then you get every single autopilot feature plus be able for the car to navigate city streets on it's own, but you still have to pay attention in case it makes a mistake.
