How to save more fuel at car drivingMost fuel economize technics can be learned in 2 lessons:
The key to low fuel consumption:
Understanding all the physics applicably for car driving.

| Lesson 1: wheel bearings defect |
Imagine Your car's front wheel bearings are defect. You hear a noise at low speed. The noise becomes louder and louder at higher speeds. When You reach 100 km/h, You think they will be irrevocably defect in the next seconds. You go behind a big transporter driving 90..100 km/h and enjoy the next tank stop. You can go in 15m distance into the wind shadow of a big truck. This is no safety problem, because big trucks have less deaccleration than small cars.
| Lesson 2: the holes in the engine's exhaust |
Imagine You have some big holes in Your car's engine's exhaust. Your car is very loud when You drive in a common style. Imagine there is a city with a policeman every 50m. Every policeman will stop You for noisiness or for driving to slow. You have to be as fast as the other traffic, but be aware, You have also to be silent despite the holes.
When You are able to drive with the holes between all the policeman without trouble, Your car will consume 25% less than DIN norm for city traffic.
Clarification: the holes in the exhaust have nothing to do with the low fuel usage. They forced me only to change my driving style, because a normal driving style is terrible loud with this technical defect. I switched to the next gear at 1500 turns per minute. I tried to roll with as less changes of speed as possible. You can see the surprising results at my Renault Espace fuel statistic in winter 1995 to 1996.

A major factor in energy usage at city traffic is speed change. You can simulate this factor in the staircase of a 14 floor high building. Let's assume 250 cm high rooms and 30 cm thick floors. You see on the left to each floor a speed equivalent.
