Are you bragging that it did work for nearly 99% of your trip, and therefore the haters are out of sorts?
Or
Are you saying it worked great until it didn’t, and your car ended in some sort of wreck?
As someone who has trialed FSD, I'd say the haters are out of sorts.
There are situations it handles surprisingly well. I drove through some road construction and FSD gracefully handled following the traffic cones that guided cars outside the painted lines. I was able to have FSD drive me from right outside my house (It won't back out of the driveway yet) to a friend's house across town completely automated with zero intervention. 15 miles of both surface streets (Including neighborhood streets with no painted lines and curbs lined with cars) and busy highway.
But there are still some bone-headed things it does. When one lane turns into two, it still sometimes gets confused and tries to drive in the middle and then suddenly decides to take a specific lane and swerves into it. It is overly cautious at stop signs and will easily piss off anybody behind you.
I truly believe that Tesla will achieve actual FSD, but it just won't be on the timescale that Elon keeps saying. I also think that FSD will eventually be Level 5 capable, but they won't call it Level 5 and still expect drivers to pay attention so they can dodge legal liability.
FSD may not be total trash, but it objectively isn’t what was promised it to be in 2020 (?)
