I have never had a problem travelling in a car. Growing up we would go to Florida every year for Spring Break and drive there and back, and often go on other road trips around the eastern part of the US.
I noticed last year when I went to Florida with my family that riding in the back of the mini-van around town made me a bit queasy. And several times over the year while riding in taxis around Europe that I would often feel queasy. It does not happen when I drive and not every time I am in the car. Reading will sometimes set it off.
Am I imagining things, or can one really develope car sickness as an adult? Or is it just perhaps becuase I am not riding in cars that often that my body has forgotten the motion? I don't get sea-sick, and nor do I get motion sickness from rides (a good thing since I am a roller coaster fanatic). Airplanes never even phase me. Its just the occasional car ride!
Anyone else have this problem?
