Personally I find trips through Paris, London and Berlin especially interesting, though driving on country-roads surely has its fans too.
Though gripping and entertaining, 3D Driving-School, first of all, helps prepare for a driving test. It supports keyboard, joystick and wheel. The latter is advisable to really turn a game into a simulator. There are 3 levels of proficiency: Rookie, Beginner (learning without mirrors and looking around), and Normal (actually preparing for the examination). You can choose a vehicle among some cars and motor cycles.
