In Moscow none of Yandex.Taxi drivers drive their own car. They drive a yellow Yandex.Taxi car with standartized livery. A lot of them have zero knowledge of the streets. I took a ride to the airport once and the driver didn't know how to use the toll road. I (who never owned a car in my life) had to explain how to use the damn thing. This is the quality of drivers we're dealing with here.
