A shame the author doesn't mention what FSD release the car he used was on? There is significant differences in performance now, especially the cars on the 12.3.x branches that have the new end-to-end route planner etc. It would be my first question to anyone reporting on an FSD experience.
Someone trying an 11.x version and someone on 12.x will have significantly different experiences at the moment, with 12.x having some of the biggest advancements we've seen since Tesla began doing this. 12.x is still rolling out to fleet now, with only ~40% of cars on it if the online Tesla fleet version trackers can be believed.
I'm not suggesting it might change the author's feelings completely if he was on a 12.x branch of FSD, but the jump from 11 to 12 has been siginificant.
EDIT: not sure why the downvotes - its a legitimate question the original article doesn't answer...
