Basic Plan:
1. Increase the tire pressure of 4 wheels to reduce friction.
2. Clean up the trunk, take home what you can, throw away what is useless, and lighten the load.
3. Go downtown less often.
4. Avoid rush hour traffic as much as possible. Better to take a detour than to get stuck in traffic.
5. In case of serious traffic jam, consider turning off the engine while waiting.
6. Bring fewer colleagues along when going home or going out (pretend not to see them).
7. Absolutely no overloading. Take one less passenger if possible: take your wife without the girl, and take the girl without the wife.
