Welcome to Germany, the land of the speed-unlimited autobahn but also the world's most comprehensive highway code enforcement apparatus. On unrestricted highways it is perfectly legal to do 200-plus mph whenever you feel like it and when conditions permit, but on main thoroughfares, speed limits are ubiquitous, automatic distance checks via modern measuring equipment mounted on bridges can cost money and your license, and, in addition to increasingly common radar traps, there are plenty of camouflaged cops ready to point their laser guns at you. So instead of getting up at 3 a.m. to find an empty stretch of unrestricted highway (and perhaps to encounter crossing deer or a hoard of stray boars), you should consider sampling the country's most challenging stretch of public toll road, better known as the Nuerburgring Nordschleife. All you have to do is fly to Germany, rent a car, buy a track ticket, and, most important, don't crash. Because even though rental cars can be comprehensively insured, reckless driving can easily void that coverage.
