Looks like this thread is about AP now, so I'll share my experience. I have a 2018 Model 3 with $5K EAP and $3K FSD bought in the original car purchase.
AP2 with FSD clearly DESTROYS AP1 in many ways, but mostly these 2 things:
1) AP2 car has cameras on sides and rear that are used during driving for safety, so automatic lane changes are much safer than AP1, which doesn't have ANY cameras on sides, just low-range sensors.
2) FSD on city streets is awesome, my car drives for long periods automatically through intersections, and stops for all stop signs and red lights.
Other nice features of FSD are:
- Navigate on Autopilot can be good in certain situations, the freeway changes are nice and I like when the car tells you when to change lanes in advance to prepare.
- I use summon frequently to move my car a few inches forward or backward when parking in tight city spots or near driveways.
- Auto parallel parking is very good, but only when offered on the screen.
Oh, and also the actual FSD software rewrite from ground up with AI and video labelling is supposedly going to launch wide within 3 months. I'm impressed by the Beta videos that are showing that.
AP1 is awesome, AP2 is great for safety but crappy for lane changes, AP2+FSD is the KING!
