I have to wonder if the geniuses who started these services ever consulted cab companies and drivers before the fact to have a better understanding of what they were taking on.
Of course they didn't. The name of the game is "disrupting an industry". Because on paper and in investor pitches, everything is straightforward, simple, and was practically waiting for them.
That reality is more messy, has more edge cases, doesn't always follow your process, is something you don't tell the investors and don't consider in your service until you've had the chance to cash out.
