My family who sit on the back repeat complain they feel dizzy and uncomfortable when I drive the car on road. So, one day I let my wife drive and I sit on the back to feel it. Result...I also feel dizzy and uncomfortable for what they complain and even feel need throw up when the car take us move more than half hour. Is that a car sick? All of our family member included me also got car sick symptom?OR...what I get info from other member said that is the suspension issue? Is it too soft or hard? Came from the spring or the absorber? Any bro know what exactly happen and how to solve the problem......to the car or to the human?TQ.
