Do you know why experienced drivers often open only one car window while driving or not?

Usually, car drivers have the habit of opening the car windows to let the air in when driving long distances. However, do you know why experienced drivers often only open one side of the windows and never both sides? The reason is that when the car is moving, opening both sides of the windows will create a strong wind force that increases the aerodynamic drag of the car. When the drag force increases, the car will have to deal with higher fuel consumption as well.

Firstly, to ensure air circulation, for drivers who drive at high speeds, opening the windows can directly impact the driver’s ears due to air pressure. Therefore, experienced drivers will open a gap in the rear window to allow the air to flow into the car and avoid the aforementioned situation.

Secondly, during driving, if the windows are always closed, the vibrations of the car will cause uneven air pressure inside and outside the car, which can cause damage to the eardrum in the long run. Therefore, opening the windows helps to balance the atmospheric pressure inside and outside the car.

In addition, many drivers often have the habit of opening the left window to better observe the rearview mirror and the traffic behind. Some even lean out of the left window while reversing to easily and conveniently observe.

Some tips for safe and fuel-efficient driving:

Remove unnecessary items from the car:

Many people tend to load all their belongings onto the car even though they have many items that are not needed. With more weight, the car will require more energy to move and will consume more fuel.

Therefore, you should remove unnecessary items to save fuel.

Drive in the correct gear:

For manual transmission cars, driving in the correct gear will help save fuel. For example, when the car is traveling in 3rd gear, it will require more fuel to maintain a speed of 80km/h.

If the driver uses a lower gear than necessary, the engine will not operate efficiently and waste fuel.

Turn off the air conditioning when not in use:

The car’s air conditioning system consumes about 15% of the fuel while driving. Therefore, do not overuse the air conditioning system. If the weather is nice, you can open the windows to let the breeze in and save fuel.

Regular maintenance:

It is not by chance that car manufacturers advise drivers to follow the maintenance schedule. Regular maintenance will help maintain the engine properly and reduce fuel consumption.

You should pay attention to some signs indicating that the car needs maintenance, such as worn spark plugs, dirt, issues related to the air filter, fuel filter, etc.

For vehicles with diesel engines, they will consume more fuel if the fuel injectors are dirty. However, many drivers do not pay attention to this sign and neglect maintenance, resulting in higher fuel costs.

Monitor tire pressure:

Experienced drivers understand the importance of monitoring tire pressure as it not only helps save fuel but also ensures safety while driving. For example, if a tire is 0.1 atm low on pressure, it will increase fuel consumption by 2-3%.

Turn off the engine when possible:

With modern technology today, many cars do not need to warm up the engine beforehand. Therefore, drivers should only start the engine when the car is ready to move to avoid unnecessary fuel consumption.

In addition, if waiting at a red light for less than 20 seconds, drivers should not turn off the engine as the car will consume more fuel when restarting.
