I get the same type of nausea described by the author. I can’t read a book or look at a screen for too long without a feeling awful. I can also get it just from sitting in a rear passenger seat, especially if vehicle has poor visibility, and even worse with a bad driver. I have to really focus on looking outside the vehicle at the moving world.
Interestingly, I think there are people that have the opposite type of motion sickness. For example, my mom could never play arcade racing games without getting nauseous. The issue being focusing on a screen with rapidly moving objects and everything else in the peripheral being fixed, versus focusing on a fixed object and everything in the peripheral moving. She never had any issue reading a book in a moving car
