For driving a car, officially, you need to have a driver's license. But, and many people don't know this, it is actually fairly easy to drive a car without a driver's license!
- first make sure that you do _not_ have a driver's license (no cheating!)
- take/borrow keys of a car
- walk to said car
- open door of said car
- sit in the driver's seat
- start the engine and check the mirrors
