Why all cars don’t have a rear windshield wiper? Many factors play into this decision, including aerodynamics and efficiency as well as fuel economy.
In bad weather conditions, an auto rear windshield wiper will provide clarity of vision in the rearview mirrors. In addition, the majority of them allow for the installation of a rear windshield wiper that improves vision in dry conditions as well. Rear wipers are standard on many hatchbacks and SUVs However, why can’t all automobiles have one?
Is a Rear Windshield Wiper Even Necessary?
There are a variety of opinions about the rear windshield wipers on cars. Some argue that because of the aerodynamic properties of the car the vehicle doesn’t need one: Windshear alone does a great job at driving snow, water, and other debris off the surface of the glass.
Others refer to the body design Its length serves to act as a buffer vehicle spray and glass, preventing it from falling on the glass.
Another view is that of aerodynamics, which suggests that the air moving on top of a car would lift the wiper off the glass’s surface and render it ineffective.
Rear Windshield Wiper Manufacturing Considerations
There are many reasons why automakers might decide to not include the rear windshield wiper. There are a few that stand out including the lack of space to store the motor behind the windshield and washer-fluid reservoir extra cost associated with this system as well as weight-reduction concerns (to ensure that the system meets fuel efficiency standards) and the increased drag (which interferes with aerodynamics and, it is also a factor in the efficiency of fuel) and aesthetic appeal.
Rear Windshield Wiper: The Final Word
The most satisfying solution is The reason is that the designer of the car decided not to make one available. What exactly prompted them to make the decision might be connected to any of the theories above according to their own set of values, customs, values, and aesthetics.
