A Tesla Model X using FSD 14.3.9 automatically nudged itself right to avoid a potential collision during a manual drive on a curve.
This real-world clip shows the tesla fsd collision evasion system kicking in when a truck passed too close. The driver had just accelerated, and the car interpreted the situation as risky enough to intervene with a slight steering adjustment.
Context from the 14.3.9 test
The event happened while Full Self-Driving was active but the driver was still in control. A brief message noted the fsd 14.3.9 intervention. The car appeared to react to the truck’s headlights and the tight geometry of the turn rather than an obvious lane departure.
Tesla has been rolling out pieces of tesla automatic collision avoidance separately before folding them into the main stack. This tesla model x evasion assist moment is one of the first clear public examples of that logic working in daylight conditions.
What it means for Tesla owners
For anyone running Full Self-Driving, the new behavior adds another layer of protection when other vehicles drift close on curves or during merges. It is not replacing driver attention, but it does reduce the chance of a sideswipe when the cameras flag an imminent threat.
I’ve noticed the same cautious edge in my own drives since the update. The system now feels quicker to create space instead of waiting for the driver to correct.

Bottom line
This tesla fsd collision evasion update is exactly the kind of quiet safety improvement that makes the full self driving safety feature more useful every week. It turned a potentially close call into a non-event without any drama.
