If you are a bad driver and you're always crashing your car and crashing into walls etc. then it's easy!
When another car/van stops at a traffic light or whenever it stops, quickly double-jump on top of the vehicle and stay put on top of it. It will keep stopping to let you off but just keep going.
Eventually it will take you at the place where you began your mission i.e. talk to Marge or someone. So just jump off or walk off. So in the end you will be safe and sound and you won't crash anything!
