Didi responded to the new policy of online car-hailing: drivers will receive sharp reductions and fares will be doubled
On the afternoon of January 1, Beijing issued the "Beijing Online Reservation Taxi Operation Service Management Implementation Rules" (solicited opinion draft). The draft for comments stipulates that the vehicles used for online ride-hailing in Beijing in the future will be limited to vehicles with local license plates. The wheelbase of the vehicle should meet a certain standard. Among them, if the online car-hailing vehicle is a fuel vehicle, the wheelbase should be more than 1 mm; if it is a new energy vehicle, the wheelbase should be more than 1 mm.
Didi’s official response to the solicitation for opinions stated: This move will lead to a sharp reduction in vehicle supply, fewer drivers, doubling of fares, and reduced travel efficiency. Didi will be strict with itself, continuously improve service quality, and provide users with high-quality and affordable travel services. At the same time, Didi also hopes that local governments can create a good environment for the development of new business formats and the sharing economy.
