What’s the difference between AutoPilot and Full Self Driving? Is FSD worth it?

Please refer to this page for Tesla’s official description of AutoPilot features vs. FSD.

It is important to note that ‘Full Self Driving” is not totally autonomous driving, nor will it be for several years to come (barring any Elon Musk-style major breakthroughs). As the driver, you are always responsible for your vehicle and must pay attention at all times.

If you do not go on long trips or do not wish to have the additional features listed on the Tesla page above, then perhaps spending money on FSD may not be worth it for you. This is mostly an investment in the future as well, but that future could be years away.

As of July 2021, you can get a subscription service for FSD for $199 per month, through the Tesla application.

I keep hearing about phantom braking. Should I be concerned?

Phantom breaking is a real phenomenon while on AutoPilot, where the car decides it needs to stop quickly for no human-obvious reason. There are many theories as to why (overpass shadows, perhaps bad GPS reading combined with inaccurate speed limit data, dirt on cameras), but nothing has really proven to be the absolute and all-encompassing answer. If phantom braking happens, it does tend to happen at the same place and time, and it can be scary. This is why it’s important to pay attention at all times.

Instances seem to reduce on each software update, and most people never experience it, but it cannot be totally discounted as resolved.
