I remember being at FlightSafety Dallas for MX initial and part of the training was APU start, engine start and taxi in the sim. If it was busy they'd leave the motion part turned off, but it was not uncommon for the instructor to occasionally let the MX guys play a little bit if no one was looking. My partner in the G200 started to get nauseous as soon as he started to taxi. We swapped seats and he started getting sick again. The instructor had us take a break and get back in with the motion turned on, I was fine, but he was not. Barf bags in a sim, it's amazing how our brains work regarding visual cues and balance from the vestibular. We both passed as far I know.
