Last Friday,1 was standing near a subway exit, tried to call a taxi. But no luck.
Then I thought of the taxi-booking app my friend has recommended and I booked a taxi through my cell-phone. Soon it came, and l stepped in, feeling pretty proudly of my high-tech way and satisfied with the convenience brought by the app. So later,1 was upset to find that the driver was busy looking his cell-phone to get the next order. It was just then when I began to worry about my safety. What’s bad, the driver’s informations might be unreliable. How can we passengers' legal rights be protecting if something bad happens? So be careful when you use the taxi-booking app the next time.
