That's how I was taught to counter motion sickness in the 80s, when we were nomadic (of sorts) and did lots of cross-country drives. We didn't necessarily have to look straight ahead, but look out the window to see the motion while consciously thinking about the fact that we are actually moving. Eg, we were told to "think about the engine pushing the wheels, and the wheels pushing the road, and that's why we're moving". 30+ years later I still use that trick on the very rare occasion when I get motion sickness, and it still seems to work fine.
