If you notice, in some cars the fuel tank cap is located at the side of the asset, the other is the fuel in the opposite position. So why is there such a problem?
The explanation is that in countries where traffic rules are right on the road like the US, turning right is often easier than turning left because there is no need to cross the traffic that is in the opposite direction . Therefore, most drivers often buy fuel at gas stations that they can conveniently turn in, ie to the right.
Suppose the fuel tank is always on the driver's side. At that time, the driver will always pair the right side of the pump head to fuel. During rush hour the right side of the pump head will be crowded while the left side is empty.
Thus, the design of the gas cover of vehicles is located on different sides so that some vehicles can park on the left or right side of the pump head. Thus, the driver has to queue in order to refuel. This benefit is much higher than the inconvenience when occasionally parking the wrong side of the pump head when using a rental car.
In case you are new to a car, or are renting a car or borrowing a car from a relative or friend, locating where the fuel tank cap is located so that when you need to refuel it is not embarrassing, it is not too difficult. .On the gas tank indicator light there will be a small arrow, if it points to the side, the gas tank cap will be on that side.
