Motion sickness: Motion sickness can happen if the signals from the brain from the eyes and from the balance sense organ (within the inner ear) and other cues are different. Differences in the function of the inner ear, vision, nervous system, or vascular system of the brain can all result in a tendency towards motion sickness to varying degrees. Everyone is different, so tendencies towards motion sickness vary.

Motion sickness: Motion sickness is due to "ocular - vestibular mismatch." the vestibular system is in the inner ear and senses position and rotation. When what the eyes see does not match what the vestibular system senses, it causes motion sickness. Some people are much more sensitive than others to this mismatch. You can reduce the issue by looking outside the boat or car. Then you have a better match.

Vestibular system: Some people have more sensitive vestibular system than others, amplifying perception of movement. Others have extremely weak vestibular system, making visual and vestibular perception of movement out of balance.

Genes: Motion sickness often runs in families. A medical study of identical twins in india showed that both twins either got motion sickness or both twins did not get motion sickness 100% of the time. Some races, such as asians are also more prone to motion sickness. The evidence is strong, but the exact genes have not yet been isolated.

Reading in the car: You're lucky. Your vestibular (balance canals filled with fluid in the inner ear) are just not that sensitive to the effects of close visual fixation while you are in motion. Enjoy your reading.
