Please don't pretend to be dumb, "predictable" in this context means that you know the final price of the trip before you start the journey, instead of having an odometer.

And randomly hoping for a taxi to drive by maybe works as long as you exclusively travel between airports, train stations, and downtowns of major cities, but if you're even slightly more remote than that you'll have to call or use some random app to get the Taxi to pick you up.
