Other 'saving weight to go faster' methods may, or may not include :
1. Only driving at least 24 hours after your last meal.
2. Only driving at most 24 mins after your last number 2.
3. Drive naked (may require the installation of privacy glass!).
4. Attempt to restrict all journeys to downhill roads.
5. Ensure any passengers lay on floor, to avoid putting extra weight on seats (they should also follow steps 1-3 above).
6. Pour a maximum of 1L fuel into tank, and refil from 50L fuel container stored in boot, as needed (For maximum benefit, combine with step 4).
7. Revove all brakes, and only drive in unpopulated areas (For maximum life expectancy, DO NOT combine with step 4!).
8. Trim finger/toe nails and hair prior to driving (subjects of step 5 should also do this).
Ok, sorry. Was feeling in a stupid mood! But hey, I didn't go off subject anyway
