Why do some cars have back windshield wipers?
Rear wipers are essentially meant for vehicles with an upright rear window that collects dust, dirt, snow, etc., because of aerodynamics – the flow of air over the right angle where the roof and rear window meet creates a low pressure area that pulls that nasty stuff in and deposits it onto the surface.
Why do some cars not have back windshield wipers?
Some that top the list: Lack of space to conceal a rear windshield wiper motor and washer-fluid reservoir, the added cost of the system, weight reduction considerations (to meet fuel-efficiency standards), increased drag (which disrupts aerodynamics, and once again, fuel efficiency) and cosmetic appeal.
Is rear wiper necessary for SUV?
SUV’s have rear wipers because the upright rear end of these vehicles tend to build up snow, dirt, and more on the rear window, that needs to be wiped away. The aerodynamic of sedans for example allow these things to dissipate while driving, while SUVs don’t have enough airflow there to stop the build up.

Why do people put plastic over their rear wiper?
The plastic bag is to prevent the air dryers from lifting the wiper and potentially ripping it off the vehicle. The idea is the air will go around the bag, and not through the wiper which typically has channels the air can “grab”.

Why do hatchbacks have a rear window wiper but sedans don t?
The Aerodynamics and Car Design
First thing is, rear window wipers are essentially meant for hatchbacks since these cars are usually designed with an upright rear window which often collects more dirt, dust, etc. than sedan cars (as well as coupe or wagon), thereby giving poor visibility to drivers.
Why do SUVs have rear wipers but sedans don t?
SUVs have rear wipers because their rear windows have a more vertical orientation that allows for dust and debris to accumulate faster. Rear wipers are used to keep the window clear and easy to see through for safety reasons. Sedans and smaller vehicles have a sloped window that prevents this build-up.
How do I wipe my rear windshield?
