It's interesting how ride hailing apps seem to benefit from literal names early in life. UberCab being the other prominent example. But later on they drop the more literal part of the name.

I've been in SE Asia for over a year now and GrabTaxi is everywhere and common in a lot of places, but I'd always side with Uber because of the cashless payments. Especially here in Saigon, I would love to use GrabBike (motorbike taxi) but still opt for Uber so I don't need to worry about paying. Excited that they've launched this!
