Every car is a compromise.
Everything negative aspect of the Insight is the result of a compromise to achieve the maximum fuel efficiency without sacrificing the comfort of the driver and passenger. Aluminum is light, but delicate Because the Insight's body is largely aluminum, I will have to be very careful not to park it where others can open their doors into it. I'd hate to see dings in those beautifully sculpted door panels. Of course the aluminum body is one of the reasons the Insight is so light and fuel-efficient. Mud flaps are not aerodynamic The rear portions of the front wheel arches are tucked in to keep them from interfering with the air flow.
