Roller blader skates 120 mph with a Dodge Challenger SRT8 assist

German stuntman Dirk Auer has a simple approach to speed: Big power, small wheels. When he's not strapping a jet pack to his back while on inline skates or riding tiny toy cars with mini jet engines, Auer shows off his bravado by grabbing onto a fast ride and holding tight. Here's his latest demonstration, shot at a German airfield last weekend, where a 592-hp Dodge Challenger SRT8 takes the daredevil up to 120 mph while he holds onto the trunk. Most of us should stick to trying to go fast while still inside the car.
