Have you tried Uber when you go abroad? They say that Uber has the same system anywhere so that means it is like a taxicab on call. I have tried Uber here in our country and I find it good especially that the fare is to be paid using credit card only. What's good is the convenience since all you have to do is call the Uber hotline and state where you are located. But in another country, I still have to try Uber. In Singapore, we always take the ordinary taxi so sometimes we have to line up in the queue of the taxi stand. The same in Hongkong where the line to the taxi stand is very long.
