I voted "yes, but only a little" in the poll-because I can tolerate a little bit of travel, and I haven't thrown up for that reason since childhood.
Motion sickness is a contributor to my inability/unwillingness to travel (at least beyond a small radius around where I live).
However, agoraphobia, social phobias/anxiety, and probably some other factors have a hand in it, too.
Car ride-it depends on the terrain and road condition-smooth interstate highways are usually the least sickening, on a vestibular/visceral level.
Twisty windy up & down and side-to-side roads-esp. with rough surface (dirt roads, many potholes & ragged pavement) are so much worse to feel, physically.
Trains sway, rattle (sounds that startle & unnerve me), rumble.
Planes-well, you know what they're like, not to mention the claustrophobia that can induce.
A bus (depending on whether it's a glorified/souped-up van or a ginormous coach) is loud-I prefer the larger buses bc. they are more likely to provide a smooth ride.
Unfortunately, in my small town, what bus service there is has small, ramshackle, creaky, clunky buses and one feels quite tossed about, jostled like cargo.
All I can say, is thank goodness I don't get motion sick when I walk ! That's my one reliable method of getting about.
