I bought the car a year after it was released and it seems to jerk at high speeds when going over minor bumps in the road. also shakes when riding through high winds. it seems extremely light weight and is hard to control if there is strong winds(15mph) present which extremely nerve wracking especially traveling long distances, or with my children, or on the highway. the jerking should not be occurring for minor bumps on the road, makes me feel the car is unsafe. *tr
