Images: Safety check for concept cars

South Korean Hyun Joon Park, a 22-year-old student, entered the Concept WL design. Hyun theorizes that SUVs and trucks give better protection during crashes because those vehicles' weight is better balanced. He uses a reinforced metal frame for the body structure with lighter synthetic carbon fiber body panels. The body's infinity-shaped structure helps protect passengers during crashes.

Another proposed safety measure is a sign on the rear of the vehicle that could display speed, direction and other messages such as "I'm a beginner" to help other drivers be prepared to respond. It looks like an electric bumper sticker.
