Your claim was that the product doesn't work, and I'm telling you it works without intervention consistently and in complicated traffic situations.
Any argument about how people don't pay enough attention since it isn't yet certified as a L4 system is irrelevant and tangential to the point.
Your definition of Tesla's self-driving product is very different than what Tesla itself promised, and that's what the person you are replying to...is telling you as well.
Anyone who thinks it is pipe dream given how it works today + rate of change is clueless, and that is putting it kindly.
I don't think L4 autonomy is a pipe dream. Indeed, it exists today and is widely available in the same city you drove your Tesla in. I think it's a pipe dream for Tesla specifically to achieve it, because for bizarre and idiosyncratic reasons Elon Musk won't let them use LiDAR or mount a roof sensor. They've been stuck at L2 for a decade now, and I don't see much reason to think that making that system incrementally more reliable will ever "unlock" L4.
In practice, Tesla on HW4 drives indistinguishably different from Waymo.
It does! A system which drives indistinguishably different from Waymo 99.999% of the time is L2. You might very well never experience that unlucky 1 mile in 100,000, but if there's 1M Teslas on the road driving a daily average of 33 miles, it's going to happen hundreds of times each day. An L4 system must guarantee that it can come safely to a stop before human intervention is required, and I don't think you can achieve that guarantee by pushing the nines on an L2 system.
I've been in Waymos that have needed teleop rescue multiple times in the last year so by that metric it's not a L4 system either.
