Are the vehicles shown above in the distance side-by-side, or are they merely on a curve? You have 3 seconds to decide, or you're dead. Or, no big deal. 🤔

When there's an oncoming vehicle in your lane 11 seconds away, do you drive immediately into the ditch? Of course not, it's a driver passing that will (presumably) return to their own lane. The imminent collision was not detectable until the distance was very short.
I should have been a little clearer. I believe the initial typical reaction of a typical driver would be to slow down, not drive into the ditch. It does not appear that FSD slowed down; instead, it waited until the very last second to swerve to the right.

From the time the double headlights appeared (0:06) to when FSD swerved right (0:12), it seemed FSD was way too slow and waited a long time.... six seconds, not three seconds to react.

Oh well, that's just my observation.

So you know when FSD really gains its advantage? When the other guy doing the passing has it. The bonehead.

Glad we have so many head on collision experts here lol

The guy lived and didn't crash. It's a win for FSD. People die in these scenarios all the time.
Far from proclaiming expertise. Overjoyed the folks in both cars are alive. Just want to know what to expect of my own FSD in various emergency scenarios that I wouldn’t want to try myself. Understanding these videos helps me with that.

Yes, that's expected behavior for both.

Human drivers still have the advantage in understanding things that are farther away.

FSD has the advantage in reaction time, but only when the perceived threat is within the effective (shorter) distance.

Any time you see "context length scaling" in FSD release notes, there's been an improvement to this.

Glad everyone was okay in that incident.

If I were to need one reason to put my family in a Tesla with FSD, this would be it.

As you view the video, the driver approaching the camera on the right side is attempting to pass the semi truck. He’s on the wrong side of the road.
Yeah. I see that. I misunderstood initially and thought this car had entered a 4 lane going the wrong direction.

The post could have been named a little more clearly. Passing improperly is not really “wrong way” driving, just improper with opposing traffic. This happens a lot in rural AZ and NM. Impatient people dying to save a few minutes in travel time, smh.

Yeah. I see it all the time, people passing in blind corners and up blind hills and this sort of thing . Very scary.

I STILL don’t understand the circumstances of this video @CyberGus.
If this is a wrong way driver it’s the Tesla that’s going the wrong way. Why is a car in FSD heading the wrong way on on what I assume is a 4 lane with a large median?
It's a TWO-WAY, Single lane each side!! The on coming truck was attempting to pass a truck in the same lane as he. However the speed and timing where way off. The oncoming truck was in the wrong.
