I went through this exercise, got the FSD Beta, used it for a month or two, stopped using it because it wasn't fully baked, sold the car, bought a new tesla without FSD beta, and couldn't be happier.
My advice, drive your car, don't let your car drive you. The FSD Beta is fun at the beginning but it doesn't last.
Lots of off topic posts lately and I know this isn't helping so I'll throw in a little investing with it.
My personal take rate is 50% on FSD and dropping. In order for Tesla to realize the potential earnings from FSD it needs to be bulletproof (like radar Autopilot was). The date that happens is anyone's guess. Nobody knows...but when that day does come (2023, 2030, 2040?) $TSLA will be the most valuable company in the world assuming they get there first.
