Agreed, it's still has a bit of ways to go. But by the time they have something substantial and it's worth it, it will be at least $10k +
GM/Cadillac is rolling out SuperCruise for a $25/month subscription, which includes $10 a month for Onstar access. So it's only $15/month or $180/year incremental. That's maybe worth about $4000 upfront if you price it aggressively.
Unless you are convinced that SuperCruise will somehow be non-comparable to FSD, which doesn't really make sense to me over time, there is no way in the world that FSD could be worth, or Tesla could charge, anything close to $10,000.
It's a double-edged sword for Tesla: if they're the only ones that have a usable FSD (someday), real FSD will never get widespread adoption. So they need others to figure it out for it to become the standard. But if others figure it out, they have to price things competitively.
Elon can't have it both ways. FSD might be going higher in the near-term, but I don't see any scenario where the longer-term trend is not down. Think of all the things you used to pay extra for, but now come standard. I'm not sure why this would be different.
