Did you follow Tesla's published instructions on how to use it (https://www.tesla.com/ownersmanual/modely/en_us/GUID-2CB6080...)? You're explicitly forbidden, for example, from assuming that it's going to make the right decision at intersections; you must manually inspect each intersection and evaluate whether it's "safe and/or appropriate" to continue. You're also not allowed to look away from the road or use your phone. YMMV, but to me that level of required attention doesn't match the term "self-driving".
replyWhat I see a lot of people do, unfortunately, is reconcile this contradiction by not following the published limitations of the "Full Self-Driving (Supervised)" product. They assume that Elon Musk wouldn't call it that if it couldn't be trusted to do what they expect. Then they get into fatal crashes, and someone sues, and Tesla argues that they can't be held accountable for bad drivers who don't follow the rules.
Your claim was that the product doesn't work, and I'm telling you it works without intervention consistently and in complicated traffic situations.
replyAny 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.
replyAnyone who thinks it is pipe dream given how it works today + rate of change is clueless, and that is putting it kindly.
replyI 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.
replyIn practice, Tesla on HW4 drives indistinguishably different from Waymo.
replyIt 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.
replyI'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.
