You will have seen the Oceania ad with two "pilots" sitting in what seems to be a flying simulator. But why is it jumping back and forth?

I have flown in a few different types of planes, from the small grumman widgeon, to the DC3, to the 747 and none of those planes vibrate back and forth like that. All the planes I have flown in have been very smooth.

So why do they show a simulator that vibrates? Very unrealistic.
