I'm a huge fan of trains and hate cars, but the motion sickness bifurcation you describe is unusual, so I would avoid trying to use motion sickness to carry water in pro-train arguments.

The vast majority of people who experience motion sickness in cars will also experience motion sickness in trains.

It took years for me to really understand why so many people don't love trains like I do: motion sickness makes the freedom, relaxation, and ability to focus on work I experience not universally shared.

Sure. In this particular thread I'm just answering two generalised statements ("Public transport is intrinsically worse", "Why can't you work in a car?") rather than making a universal case.

I'd be genuinely interested to know stats for car and train motion sickness, though: I haven't found any on a quick Google. Motion sickness in general appears to be ~30% of the population. Obviously it's not a simple scale: my wife, for example, will get car-sick (without reading) on a fast, bendy journey more easily than I will; neither of us get train-sick; I get sea-sick much worse than she does.
