I just booked a Uber X and was going to travel a distance of 10 km . The ETA showed 5 mins but the driver was alreddy there at the location . I hopped in . Soon after some kilometers he provided us WiFi . It was quite unusual beacuse thses days even WiFi Cabs dont have WiFi . There was no Uber Go available so I had booked X . The driver then suddenly stopped and billed up . I asked we have to go 2 kms more why did he do so ? He told be relieved and there was no problem . He soon dropped us at our location and beacuse of him atleast about some bucks were saved . The questiom was not of bucks but the driver . We can find these drivers too rarely . Simply it was unbelievable and amusing and didnt knew if any driver was so so good .
I observed the same with ola/uber during airport drop.
Probably it helps them find next customer soon, and avoid parking charges.
Also observed them missing u-turns deliberately near airport, which adds 2-3km extra.
