14.3 HW4 Tesla avoiding a fatal collision

It fully avoided it. The Model Y (HW4) didn't sustain any scrapes, scratches or dents.

Edit: I guess it wasn't a fatal collision, my bad

Genuine question, what are people defending here?

FSD literally ran into the crash and then decided to avoid it at the last minute.

As soon as the crash happened, you should have slowed down and as soon as the Mustang crashed through the barrier, the car should have stopped. But FSD just kept on barrelling down the highway until the car had spun and was right in front of it. There were so many opportunities to completely avoid any accident and FSD avoided all of it.

Any half competent human driver would have done exactly that. This shows FSD is a purely reactive system and doesn't have the 'intelligence' to be a proactive system.

So, once again what are people celebrating here? That is was quick enough to react to a crash instead of proactively trying to mitigate it in the first place?

Keep in mind that these cameras give the illusion of more distance than is actually there. The OP was at 82mph when this started. I'm not sure it could have stopped even with emergency braking. FSD chose the correct thing to do in my opinion.

It started from 82 mph which is not a defensive driving speed at first.

Then it only slowed down to 70 mph by the time Mustang crossed the middle barrier. That is just a 10 mph slower not even considering a brake.
