As a very first AP2 costumer where you could upgrade to EAP from the regular AP, I'd say waiting is by far the best option. Only with v9 do we have actual parity to AP1. That took nearly two years when the promise was a couple of months. There still isn't a single EAP feature that works and is released to everyone. I paid an extra $2000 two years ago for nothing so far. If I'd gotten FSD, it would have been an extra $6000 for nothing. Before FSD is close to offering something substantial, it will be another couple of years at best. As good as AP is, it's not even close to being able to drive on a standard highway without oversight; the leap from this to regular roads is in order of magnitude. The new chip that will make this possible will be released in six months according to Elon. If past timelines are any indicator, this means in one year at best, and even later for those seeking upgrades to AP2x. By then my car will be at least four years old. Maybe I will have wrecked it.
Two years ago I decided to buy $4,000 of Apple stock at $110 instead of FSD. Today that stock is worth about $8,000. When FSD actually works, I will sell that stock and buy it. By then, I'm pretty sure I will be able to buy FSD and have lots of left over money. It doesn't take much sense to tie thousands of dollars for a feature that doesn't exist yet, especially when it's connected to a car that can be wrecked any day, and depreciates every minute.
Your anecdote doesn’t reflect the present.
I was in same situation. AP1 car upgraded to EAP. I passed on FSD and I put the 3000 elsewhere.
In retrospect, it was a good move.
However, It’s not 2016 anymore but late into 2018.
Will AAPL double again before AP3 chip is out?
