Using Car as Mobile Toilet

There are situations where cars are used as mobile toilets, and car companies also have relevant designs.

Improper Use in Real-life Cases

In real life, there have been uncivilized behaviors where passengers use taxis as mobile toilets. For example, an elderly woman insisted on urinating three times in a taxi and claimed it was because the driver refused to carry her to the toilet. This behavior not only seriously affects the cleanliness of the car interior, causing great distress and cleaning burdens for the driver, but also reflects that some passengers lack basic public moral awareness and do not consider the adverse impact of using the toilet in a relatively enclosed space like a car on others.

Designs by Car Companies

• Seres: Seres has obtained a utility model patent for a "vehicle-mounted toilet and vehicle". Its designed vehicle-mounted toilet adopts a slide-rail design. It is usually hidden under the front passenger and driver's seats. When in use, it can be pulled out with one button and pushed back into place after use. It is also equipped with a series of relatively complete facilities, including a 5L sealed feces collection tank that can effectively collect excrement and prevent leakage; a negative-pressure deodorization system that can reduce odors in the car; a constant-temperature heating function that enhances user comfort; disposable toilet bags that facilitate cleaning; and a foldable privacy curtain that protects the privacy of the user.
• Jishi Automobile: In 2024, Jishi Automobile launched a vehicle-mounted toilet accessory. It is placed in the central storage compartment. When in use, one only needs to lift the lid and place a toilet seat cover to use it. The design is relatively convenient and provides certain convenience for users with special needs.

Potential Problems

Although these designs that transform cars into mobile toilets have a certain degree of innovation and practicality, they also face some potential problems. For example, the frequency of use may be low. Most people will not choose to use the toilet in a car when normal toilets are available. The experience of using the toilet in a car may not be good. The space is relatively small, and movement is restricted. The odor problem is difficult to completely solve. Even with a deodorization system, some odors may still remain. In terms of privacy, although there is a privacy curtain, in the relatively special environment of a car, users may still feel uncomfortable.
