Susceptibility to motion sickness

In regard to the staff report Why do people get car sick?: Is there any objective measurement of susceptibility to motion sickness?

I think we’ve all encountered people who get car sick relatively easily, and while traveling, I’ve noticed that in some parts of the world the native population seems to be particularly prone to this malady (it makes Nepali bus rides a joy–I’m telling ya…).

But how would you test to see if a particular person or group is more or less likely to become car sick than others? Does NASA check for this with their astronaut candidates? Or does NASA just try to train/desensitize their astronauts, so they have fewer problems?

Apparently NASA regards space motion sickness as just “one of those things”.
