Why do I get 'car sick' when reading a book in a moving car?

Whenever there's a disconnect between what your eyes see and what your sense of balance detects, your body is hardwired to interpret that as poisoning, hence the nausea.

 The trick to reading in any vehicle is to look out a window when you turn, speed up or slow down so your eyes and balance stay calibrated. When the car is moving at a constant speed, you can read without nausea.
