Yeah I’m not claiming the poster is lying…but something isn’t right. The described behavior is not characteristic of v12 running properly. Maybe the car needs a reboot, calibration, or something else.
I interpreted the post as taking a few minor but real v12 flaws, and overexaggerating them for attempted comedic effect.
The current state of FSD (to me) is that it's incredibly mind-blowingly amazing, yet at the same time, not nearly where it needs to be. The incredible part is the super-wide ODD and general competency at most things, including a very humanlike driving style much of the time. The "not nearly" part is for still having to disengage every couple miles for simple, sometimes inexplicable mistakes, such as trying to drive straight from a well-marked left-turn-only lane, or being oblivious to large potholes, or being inadvertently rude to other drivers. (Also for making me goose the accelerator far more often than I'd like, which sometimes makes it feel like I'm manually controlling the speed with one-pedal driving, to the point that all FSD is doing is side-to-side lanekeeping.)
It's been observed that most airplane crashes are typically the result of about seven compounding mistakes, any small subset of which would be minor on their own. Car crashes also often involve multiple mistakes; a combination of one car doing something unexpected, and another car not paying attention or not being able to react in time to take evasive action. As such, reducing car crashes may ultimately be as much about reducing common minor mistakes (e.g. doing something erratic or unexpected, even if not illegal or directly dangerous) as it is about reducing the rarer major mistakes. This blurs the line of what constitutes a "safety intervention": if driving predictably enhances safety, then driving erratically decreases it. An intervention could thus be considered a "safety intervention" without having to be an "imminent collision intervention", at least in my book.
As incredible as FSD v12 is, I still believe it's many years away from full L4, and probably will never reach it with the current hardware stack. So the question becomes, what constitutes useful L2 (or L3)? I think that useful city-streets L2 will be when the most common head-scratching failures are solved; turning from incorrect lanes, ignoring lane guides, being oblivious to large potholes and road debris, irritating other drivers. The car needs to drive in a way that combines efficiency (proper speed and lane selection, and accepting the right of way) with being polite to other drivers and not getting honked at. When FSD can regularly do a 10-mile drive through complicated urban traffic and street patterns without making me wince, I'll consider that useful city-streets L2. (It's already useful L2 on highway, and has been for several years.) Bring on v12.4, I can't wait!
