This.

I used to take a coworker on kamikaze night runs up and down the california coast in my track car. He would envision he was driving to avoid motion sickness. Imagining braking, steering, blipping the throttle, shifting gears, operating the clutch, everything as if he were playing a video game.

One night I decided to test it and started driving poorly, braking early for turns, picking the wrong gear, or just not accelerating hard out of the corners.

He became angry and sick immediately, we had to keep pulling over for him to vomit. It was uncanny, we had been doing this stuff every weekend for months without any motion sickness issues ever. The moment I started driving unpredictably - it wasn't even driving poorly, just not what he expected, he fell apart.

I do this as well and it doesn't always work like you described. Unexpected breaks are the worst. I also feel less sick if I am sitting/standing sideways to the direction of motion. Somehow I don't feel motion-sickness at all on water, air or trains, but just on road.

Most taxi rides give me a strong motion sickness, while regular car rides do not. My assumption is this is due to the more aggressive and unpredictable driving style (quick, unexpected lane switches and turns), so I think this more or les correlates with your coworker's experience.
