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.
