alt Hacker News> And it's why reading in the car gets some people so horribly sick.
As a kid, I was told to turn 90° so that the back and forth of my eyes reading were in line with the motion of the car. This was soooo before any kind of electronic devices. Hell, the radio in the car still had the giant push buttons for saving stations.
what I was taught (and what still works for me) is to look out the front window, never the sides, and pick a as far away (ideally on the horizon) to focus on.
the theory being, at constant velocity in a straight line, your body feels at rest, so you want to look somewhere that reinforces that. looking out the side window has scenery rushing past, which is the opposite.
turning sideways and reading sounds like a nightmare.
