According to the driver it was on FSD, and it was using the latest software update available.

They can’t stop and ask for assistance at 100km/h on a highway.
Maybe the point is then, that Tesla FSD shouldn't be legally used on a highway.
But it probably shouldn't be used anywhere, because it's faulty as shit.
And why can't is slow down to let the driver take over in a timely manner, when it can break for no reason.
It was tested in Germany on Autobahn where it did that 8 times within 6 hours!!!
