Small weight-shift error, big impact. One trick that fixes it.
Almost always a hidden pelvis asymmetry. One leg carries more, usually the standing leg from daily life. At low speed it doesn’t matter. Above 30 km/h the stronger leg pulls.
Fix: stand parallel, lift each ski for 5 seconds. You’ll feel which leg is heavier. Then ski straight and consciously add weight to the weaker one. Drift disappears in 3-4 runs.
