Higher frame rates and resolution seem to mitigate the problem.
For example, if you are sitting inside a golf-cart, moving through a facility at a fair clip, and looking around, you won't get motion sickness (most likely).
But try to replicate that, at far slower frame rates and resolution than the human eye works in real-space, then you start to get a lot of the vertigo and I-want-to-vomit feelings.
So... it's not just a factor of moving while your body is not moving. Although that can still play a role. It's also a factor of additional effects, namely related to frame rate and resolution.
Which will be solved with increasing computing power.
