What is it about some cars......

That make some people feel sick?
I never get motion sickness when in planes, on boats on trains, or whilst driving, but as a passenger I have felt a bit queasy in a few. Off the top of my head these include:
LR discovery3 driven at reasonable speed in the country
honda covic type R - trundling around town
Back seat of Rav4 negotiaing the A12 around ipswich
1977 VW polo (in 1977)country lanes in Wales
I'm struggling to se the link between these cars, I guess its probably around the damping of motion, but I would have expected the honda to do well with this - it could have been too crashy i suppose
but I have covered may thousands of miles as a passenger in a variety of french cars from the 60's, 70's and 80's, most of which have no discernable damping and been completely chunder free

I get horribly sick as a passenger in any smooth riding cars, especially in the back.
Roller coasters are fine (except the one at thorpe park in the dark - thought I was going to be the first recored death by motion sickness).
Even flying in small 4 seater aircraft with turbulance - if I am flying then I'm fine but as a passenger I get sick.
I think it is to do with a combination of smooth but constant movement when not in control e.g. not anticipating it.

Is your vision perfect ?
Mild discrepancies, which would not normally need to be corrected can also cause this feeling. I have had that problem.
Also, sometimes you are more attuned to a certain level of motion, and the change could throw you off.
When I went from driving a Z4 to a 335i, I feel a bit off for the first hour or so - but that could be due to my vision, as above.

I have had travel sickness literally from my first ever ride in a car, being taken home from hospital when I was a couple of days old.
I am unable to travel in the back of any car, and I cannot use buses/coaches at all. I am ok on planes, but boats are hit and miss. Fair rides, apart from the Dodgems, are a big no no too.
Even as a front seat passenger, if I try to read, write a text message, read a map (which I cant do at the best of times) I do not just feel sick, I am sick. It makes me violently ill.

The Wookie said:
Speculation but probably a combination of ride natural frequency and damping
The right frequency to induce motion sickness (probably quite low), and underdamped so the car oscillates a fair bit
This ^^^^The right frequency to induce motion sickness (probably quite low), and underdamped so the car oscillates a fair bit
There was a documentary a while back where Dave Minter (ex-Lotus guru) talked a little about this sort of thing. It's possible to set up a car so that the natural frequency coincides with what makes people feel ill. I am not sure what that was (memory like a sieve)- if I recall correctly it's something like 0.5-1Hz?
Anyway, I recon wookie is right on this.

Occasionally feel a bit sick after an hour or so of pissing about on my iPhone or reading a book or something in the back of a car.
Only time I've ever felt a bit queasy is after being thrown about in the passenger seat of a couple of Porsche GT3 RS' around Silverstone. The drivers weren't holding back on the corners and when I got out of the second or third I remember needing to get some fresh air for a few minutes!
