The most stable build we have run so far. Early days, but the 14.3.12 regression looks resolved and speed discipline in Standard is much improved.

What changed from 14.3.12
| Behavior | 14.3.12 | 14.3.13 (so far) |
|---|---|---|
| Unnecessary right-turn-lane signals | Regressed Late in its run, signaled for right-turn lanes with no reason to move over | Not seen No unnecessary signals since the update |
| Standard mode speed | Watch Not logged for 14.3.12; earlier builds crept well past the limit | Better Stays much closer to the posted limit |
| Hurry mode on the highway | Not noted | Good Confident and appropriate on the interstate |
| Overall stability | Mixed Right lane better, exit timing late | Steadier The drive as a whole feels more stable |
How it drives
Toward the end of our time on 14.3.12, the car started to regress: it would turn on the right signal for a right-turn lane when there was no reason to move over. That surprised me, because I thought 14.3.12 had already settled that behavior.
So far, 14.3.13 appears to have fixed it. We have not seen those unnecessary right-turn-lane signals since the update, and the drive as a whole feels more stable.
Standard mode respects the limit. It is doing a much better job of staying near the posted limit instead of running well past it. That was one of my longest-running concerns; on 14.3.9, Standard crept from a posted 35 toward 45 mph.
Hurry mode has been good on the highway. On our interstate drives it has felt confident and appropriate for the road.
What we are still watching
Because 14.3.12 seemed fixed before it regressed, I am treating this as an early, dated observation rather than a final verdict. I am hopeful it points to more stability from release to release, and I will keep logging what we see.
- Whether the unnecessary right-lane signals stay gone over more miles
- Exit-lane timing, which ran later than I preferred on 14.3.12; I have not reported on it for 14.3.13 yet
- Stop-sign pauses and right-turn-lane selection from our 14.3.9 notes

Questions about FSD 14.3.13
Is Tesla FSD 14.3.13 better than 14.3.12?
In our Model 3, yes so far. Late in our time on 14.3.12, the car began signaling for right-turn lanes when there was no reason to move over; 14.3.13 appears to have fixed that, and the drive feels more stable. This is an early owner observation from October 31, 2026.
Does FSD 14.3.13 follow the speed limit in Standard mode?
Much better than before in our car. Standard mode stays much closer to the posted limit instead of running well past it. The driver remains responsible for speed at all times.
How is Hurry mode on FSD 14.3.13?
On our interstate drives, Hurry mode has been good: confident and appropriate for the highway.
Can I try FSD 14.3.13 for free?
If you already own or lease an eligible Tesla and have not had an FSD trial or paid subscription in the past 12 months, Tesla's FSD referral program may give you a one-month trial in the Tesla app. See how it works.
Supervised means supervised. FSD (Supervised) requires an attentive driver ready to take control and does not make the vehicle autonomous. These are dated observations from one Model 3 on our own routes; behavior varies by vehicle, hardware, build, location and conditions.
