4-5 years ago, on multiple business trips to India I had the following experience about 30% of the time. Order an uber, watch it get about 5 blocks away on the screen, and start driving in circles. I believe it was spoofed GPS because sometimes you could clearly see that no car was really there, or even walk right up to the spot on the map. If you send a message they say they are almost there, repeatedly. Finally after 10 minutes you give up and cancel, getting a charge. Then when you try again the same driver will come from about 1km away and actually pick you up.
