It takes a serious case of bad driving, tiredness and vehicle choice to get it for me in a car. Can play games and read books in a car happily enough, though it can get a bit unpleasant. I prefer to look out of the window. Last time was many years ago. Had just got off and awful plane ride (if I had possessed a pencil it would have gone down my ear to stop the pressure), not slept in about 30 hours, had been to a restaurant and then got in a bumpy old van to drive round and round roads up a mountain. Felt less than good there.
Put me on a boat and... it is like I am drunk except without the fun parts of being drunk.
Playing games... I had my projector on the wall and was standing off angle for it. Skate 3 made me want to look away.
Never once had a film make me feel like it even during the height of shaky cam (though to be fair I grew up watching skateboard videos so most let's knock off Hollywood/Jason Bourne stuff was not even close). Have had a few goes with active and passive 3d during the earliest roll outs and later still. Fine with that.
Roller coasters. All day long and give me more afterwards.
Had a go on one of those spin you round in a ball/series of rings things. I stopped mostly because the guy spinning it looked like he was about to pass out from tiredness.
