Having just done an Interstate trip yesterday I think it is the nature of the beast (is there an echo in here?). These cars are sensitive to the wind and to turbulence from trucks, and they need to be driven every minute; they are not cars where the driver can have his left elbow on the window sill, left hand on the wheel and a cup of coffee in his right hand. They are no worse, IMHO, than other cars their size and weight, but if a person doesn't come from a small car background they will require some changes in driving habits.
