Chapter 11 Question ○○7

Why do some cars have the fuel tank on the driver's side and others on the co-pilot's side? (Pato. Yu) One of the most frustrating experiences of renting a car is pulling over to the gas pump as you would normally do with your own car, only to find that the gas tank is on the other side of the car, out of reach of the nozzle. In fact, car manufacturers only need to uniformly set the oil filling hole on one side of the car to solve this problem.But why don't they do it? In the United States and other countries where vehicles drive on the right, it is easier to turn right than left when crossing a street.Therefore, most drivers will refuel at the gas station that can turn right into the station.Assuming the fuel tank is always located on the driver's side of the car, the driver must park to the right of the fuel pump in order to refuel.That way, during rush hour, all the right-facing pumps would be full, while most of the left-facing pumps would be unused.

Therefore, the refueling holes of different models are located on different sides, which means that some cars can refuel from the left.So drivers don't have to wait in line for refueling.This benefit (benefit) is obviously much greater than the cost of accidentally parking in the wrong direction while refueling the rental car. In some cases, product design must not only conform to how the product may be used, but also what kind of information the product hopes to convey to users.The following two examples show that the information conveyed in a certain form is more easily absorbed by people, or its cost is lower.
