If we describe HW4 as 99% of the way to true FSD, then HW3 is probably 95% of the way.
Though approaching 100% (maybe 2x the human standard) is going to be exponentially harder to get to.
I don't think Tesla can honestly claim 99%, or 95%, or even 50% of the way to FSD until they solve these issues. Until they do, it's just a fun toy. After all, years ago they were claiming that you'd be able to "summon" a Tesla sans driver from LA to NYC. What happens if there's a winter storm on the way?
What part of that final one per cent includes "will not blow through railroad crossing gates when a train is approaching"?
Or "will work in a Pittsburgh winter's night on a snow covered, poorly line marked road"?
If we describe current LLMs 99% of the way to AGI and full sentience then https://en.wikipedia.org/wiki/ELIZA was probably 90% of the way.
In this case the final 1% is 200x harder than getting to the initial 95%.
