Rear Wash and Wipe only for hatch backs?

Question

Why the rear widshield washer and wiper only for hatch backs, station wagons, SUV and mini vans, why not for sedans, because of the inclination of rear windshield?

Answer 1

Hatchback is term describing an automobile design, consisting of a passenger cabin with an integrated cargo space, accessed from behind the vehicle by a tailgate or flip-up window. The vehicle must have at least two rows of seats, with the rear set able to fold down to increase cargo space.

Hatchback vehicles are functionally similar to station wagons (which are intended to carry large volumes), but distinguished by a smaller load area. Some vehicles achieve this by having little car length behind the C-Pillar and thus no room for a side window over the load area. Others achieve this by a steeply raked rear window - a style also known as a liftback. All liftbacks are hatchbacks with a fastback profile.

The tailgate is also referred to as a hatch. Hatchbacks are often described as three-door (two entry doors and the hatch) or five-door (four entry doors and the hatch) cars. In Europe, city cars, superminis, and small family cars are usually hatchbacks.

Small cars often incorporate a hatch tailgate to make the best use of available space. Especially in smaller models, hatchbacks are often truncated, with the tailgate nearly vertical, to reduce the car's footprint. This is an important consideration in countries where small streets and traffic congestion are factors. Hatchbacks frequently include fold-down rear seats, which enable a substantial portion of the interior space to be used as a cargo area. Usually, the rear seat can be folded partially (for instance 1/2, 1/3 or 2/3) or completely to expand the cargo space.

Hatchbacks typically have a parcel shelf: a rigid shelf covering the cargo space that is hinged behind the rear seats and lifts with the tailgate. An alternative is a flexible roll-up tonneau cover.

High performance variants of hatchbacks are now common, known as "hot hatches".

Answer 2

In Hatchbacks, there is no dickey, or boot, so dust and dirt sprays on to the rear windshield, so wash/wipe is needed. Sedans have a dickey/boot, so dust is not sprayed onto the rear windshield, so rear wash/wipe is unnecessary.
