I've been reading about the Frex motion system. It looks impressive in
the video! Lots of movement.

Has anyone discussed the inaccurate motion cues that Frex system
provides? The Frex system is generating motion cues opposite from what
occurs in real life!

For instance, the inner-ear sensations that the driver experiences will
all be reversed from real life. Also, the pressure and tension changes
the driver feels between his body and the seat while the seat is in
motion are reversed from reality.

The Frex approach seems to be to move the head of the driver around in
the way it would in a real car. From that perspective the system seems
OK, except that eye position movement of the driver is already modelled
in current simulations. I guess you could just turn off the simulated
head movement in the simulation while using the Frex system.

Still, I'd hate to train and practice in that device, then jump in a
real car expecting to go fast!
