Recently, many netizens have reported that "it's becoming increasingly easier to book a foul-smelling car through Online Car-hailing," stating that this phenomenon is particularly prominent in winter, and the related Topics briefly trended on hot searches. Some netizens complained that "booking Online Car-hailing is like crawling into the driver's bed," which resonated with many passengers; others noted that especially for cheaper special express cars and regular express cars, the probability of booking a foul-smelling car is relatively high. Currently, DiDi is carrying out a special governance program for "foul-smelling cars" by launching a feature to blacklist these cars, suspending service and training for drivers with higher negative reviews about the car's air quality, and implementing positive incentives and assessments for drivers' services, aiming to improve the user experience. DiDi Travel has stated that the "blacklist foul-smelling cars" feature has been launched nationwide. If users encounter a bad experience during their ride, they can operate through the DiDi app's itinerary page to ensure they do not ride that vehicle for the next 12 months.
