Drive the World's Fastest Roads

Modern sports cars can hit 200 miles per hour right off the assembly line, but you're lucky to crawl more than 60 mph on your commute. Take heart: If you're willing to travel, you can find a playground for the lead-footed on almost any continent. These are well-engineered roads with sporadic law enforcement and a high straightness index. They're in places where fairly consistent temperatures prevent car-tossing pavement buckles and there's no danger of road salt corroding your $200K engine-with-wheels. In these pace havens, speed limits are just a running start.
