on demand car hailing = taxis?
So Singapore is one of a few cities where that's the case (NYC also -- Uber doesn't really work there. I was there for 8 days and requesting an Uber as a 10-15 minute wait. You can get into one of a million cabs that go by in that time. I gave up).
edit: which is exactly why the city rolled out the green cab system, which has inverted limitations on where they can accept street hails
And let's not even talk about the number of times a cab driver straight up refused to take me to Brooklyn, both during the day and late at night. Totally illegal, but it happens all the time.
In contrast, Uber took less time and required no negotiation.
