There are plenty of FSD videos on YouTube where the driver didn't have to intervene at all on long trips, where the car isn't just following the car in front.
You hit it on the nail, the driver didn't have to intervene but they had to be ready to take over at any time. If FSD could safely operate where you had 10 seconds to take over for level 3, why doesn't Tesla go get it certified for L3 driving. FSD isn't even approved for being a drivers aid(hands off, eyes on) in EU and China because Tesla has not demonstrated that it is safe. Even Blue cruise is approved in EU for comparison. And it isn't because Tesla isn't trying to get ADAS certification in these markets.
Are they? they haven't start certification for self driving any market? It seems FSD is more of way to pump the stock. Mercedes is testing their same cars for L4(point to point) in china.
For past decade, with meh results consistently so far. They were/are? selling FSD as premium package and never delivered on promises, that's outright fraud in plain sight.
Technologically Tesla is far behind since one man's ego wants to trump physics and computing limitations and its failing. Still no Lidar.
I don't care about 90 youtube videos of long drives with no intervention. I care about a million out of a million (and maybe 10 on top). Either there is something I can trust with mine and my kids life with, or I am not interested with anything on top adaptive cruise control (since I don't spend my life in stop&go traffic).
