Shared Car: The Mobile Toilet

Shared cars are dubbed 'mobile toilets' primarily due to the deterioration of in-car hygiene caused by the uncivilized behavior of some users, leading to even extreme incidents.

1. Uncivilized Behavior Directly Damages the In-Car Environment
As a form of public transportation, shared cars are used in temporary and open scenarios. However, some users lack public awareness and treat the car interior as their private space. For example, finding feces in the trunk, chewing gum stuck to seats, and used tissues hanging from the steering wheel are all acts of malicious damage to in-car facilities. These behaviors not only cause physical damage but also make thorough cleaning difficult (e.g., gum adhesion, fecal penetration), significantly degrading the experience for subsequent users.

2. Extreme Incidents Exacerbate Negative Labels
Although extreme cases like 'using the car as a toilet' are rare, their amplification through social media has reinforced public stereotypes about hygiene issues in shared cars. Such incidents reveal some users' disregard for public resources and even their perception of shared cars as 'ownerless spaces,' further damaging the industry's image.

3. Operational Model Flaws Indirectly Enable Problems
Shared cars employ a 'self-service pick-up and drop-off + unmanned inspection' model, which improves efficiency but lacks real-time supervision. Users do not face staff inspections when returning vehicles, leading some to believe their destructive behavior will go undetected. Additionally, the long cleaning and maintenance cycles mean that damaged vehicles may remain unaddressed for extended periods, creating a 'broken windows effect'—subsequent users, upon seeing a dirty environment, are more likely to lower their own behavioral standards, perpetuating a vicious cycle.

4. Hygiene Issues Hinder Industry Sustainability
Poor in-car hygiene not only reduces user experience but also increases operational costs for companies (e.g., deep cleaning, vehicle repairs). In the long run, if uncivilized behavior is not curbed, public trust in shared cars may decline, hindering the industry's healthy development. Therefore, a combination of technological measures (e.g., in-car surveillance, credit scoring) and user education is needed to promote civilized car usage.
