Well I looked up tramlining and this is road surface related. The car does go left or right depending on the road slope but this is not the problem. Our previous car did the same, the problem with this on the X1 is the very heavy steering which makes you work a lot correcting this movement.

The problem I am referring to is vertical and rotational movement. The car is transmitting the smallest imperfections in the road to the passengers. Bumps, holes, ripples in the surface, hardly anything gets taken out of the ride. The vertical movement is virtually constant. The rocking comes from one wheel (or one side) passing over an imperfection and instead of the socks talking the energy, the car rolls.

It is this virtually constant vertical and rotation movement which is making us sick. The headaches probable come from all the bouncing vertically. You just need to put a finger on the back of your neck while moving in the X1 to feel the amount of strees being transmitted up the spine to the base of the head.
