Why does reading in a car [while its turned on] give you headaches?!
Question: This is a case of motion sickness.
Motion sickness is a very common disturbance of the inner ear that is caused by repeated motion such as from the swell of the sea, the movement of a car, the motion of a plane in turbulent air, etc. In the inner ear (which is also called the labyrinth), motion sickness affects the sense of balance and equilibrium and, hence, the sense of spatial orientation.
Motion is sensed by the brain through three different pathways of the nervous system that send signals coming from the inner ear (sensing motion, acceleration, and gravity), the eyes (vision), and the deeper tissues of the body surface (proprioceptors). When the body is moved intentionally, for example, when we walk, the input from all three pathways is coordinated by our brain. When there is unintentional movement of the body, as occurs during motion when driving in a car, the brain is not coordinating the input, and there is thought to be discoordination or conflict among the input from the three pathways. It is hypothesized that the conflict among the inputs is responsible for motion sickness.

i think someone told me this, something about focusing on reading the small words whilst the car moves and iuno...
sorry, wasn't much help

One explantion is: If the car is standing still, perhaps you are inhaling the emissions from the car such as carbon monoxide. This would make anyone get headaches, dizziness, etc. That is why it is dangerous to stay in a confined space, such as a garage with the car running. Hope this helps!
