Do you mean FSD or Autosteer (or Autopilot or whatever it's called now). I think Tesla left Autosteer purposefully crappy. FSD is excellent at keeping the lane, way better than what your Škoda can do.
I am used that demo shows best features of the product…
Maybe they did some market analysis. I find the idea that a shitty autopilot will trigger FSD conversions to be very optimistic.
