1) Tie helium balloons to the roof rack to lighten your car.
2) When stopped at a red light, sneak out and attach a tow rope to the guy in front.
3) Take shortcuts through parks, gardens and farms whenever possible – a piece of corrugated iron welded to the front of your car will help get through fences (a la The A-Team).
4) Every few miles, pretend you’ve broken down and ask a passerby to give you a “push start” for a couple of hundred yards.
5) If your destination is near a hospital, don’t drive at all: simply feign a heart attack, call 911, then jump off the stretcher and run away when you get there.
