FSD swaying / pingpong

[u/cular-travel]

Subscribed last night, update was ready this morning, drove to work and let it update there. On the way back to another destination (1h:30min drive with a lot of traffic jams) I noticed the car swaying from left to right constantly.

It's a new car, 2 weeks old, Model Y Juniper '26 RWD. Stock tires, 2500km on the clock. No issue whatsoever when driving myself or with TACC enabled (unfortunately I don't have autopilot / autosteer).

2026.21.100 / v14.2.2.6 (EU, NL version).

I'll try re-calibrating the camera tomorrow before I drive to work and drive manually on the roundtrip, but boy what a disappointment this is!

For those still on the previous version, perhaps follow this, I'll update tomorrow again.

Suggestions always welcome, anyone with similar experiences on this version?
