The lack of windshield wipers on side doors has puzzled many drivers, but a closer look at design considerations and safety concerns reveals the reasoning behind this design choice.
Raindrops keep falling on the car’s side doors, but why don’t they have wipers like windshield wipers? This question has puzzled many ‘drivers’.
Windshield wipers are an essential component of a vehicle's safety features.
They consist of a rubber blade attached to a metal arm, which is connected to the steering column or a separate linkage system.
The wiper blade sweeps water and debris from the windshield, improving visibility during rain, snow, or other inclement weather conditions.
Most modern vehicles come equipped with two-speed or intermittent wipers, allowing drivers to adjust speed according to the weather.
Regular maintenance of windshield wipers is crucial to ensure optimal performance and prevent accidents.
The main reason cars don’t have wipers on their side doors is due to design considerations and practicality. Windshield wipers are typically designed for the front windshield, which faces a different set of environmental conditions compared to the side windows. The side windows are exposed to rain and debris from the ‘driver’s’ and passenger sides, but they also receive sunlight and heat from the sun, which can cause the glass to become foggy or misty.

Additionally, the side doors are designed to be more compact and accessible than the front windshield, which requires a different type of wiper mechanism. The wipers on side doors would need to be smaller, lighter, and more durable to withstand the rigors of daily use.
Another reason cars don’t have wipers on their side doors is safety concerns. If the side windows were to fog up or become misty due to rain or condensation, it could impair the ‘driver’s’ visibility while driving. This would be particularly problematic for drivers who are already distracted by other factors, such as navigating through heavy traffic or dealing with inclement weather.
While car manufacturers may not have wipers on their side doors, there are alternative solutions available to help keep the windows clear. Many cars come equipped with rain-repellent coatings or treatments that can improve visibility during rainy conditions. Some vehicles also feature heated windshield and side window options, which can help prevent fogging and misting.
In conclusion, the lack of wipers on car side doors is largely due to design considerations, practicality, and safety concerns. While it may seem like a minor oversight, these factors contribute to the overall design and functionality of modern vehicles.
