Car sickness
Well theres always exceptions even among auspies there are differences in sensitivities and levels of dyspraxia.
But given that most auspies are somewhat dyspraxic making it difficult for them to subconciously adjust their bodies to absorb the external forces and decrease the amount of movement registered by the inner ear as NTs tend to do and the fact their sense of balance is often over or underdeveloped, it being common is not that far fetched.
I have found a document explaining exactly that:
http://www.aspergerinfo.org/AspergersSy ... yeView.pdf
"Many people on the autism spectrum have sensory integration disorder (SID).
SID is hyper (too much) or hypo ( too little) information from the senses. Hyper
sensitivity to tactile sensation would be the person who is bothered by the seam in their
socks or tags in their clothing. Hypo sensitivity to tactile sensation would be not noticing
a blister forming from shoes that didn’t fit well. Examples include
Hyper sensitive to sound
Music is too loud and kid has hands over ears complaining
Hypersensitive to light
Kid doesn’t like going outside on a bright day, squinting.
Hypersensitive to vestibular
Kid gets car sick or doesn’t like park rides. Who wants to go to Six Flags? Not me
Hypersensitive to smell
Walking down the detergent aisle at the store is difficult, kid covers his nose."
