The telling thing to me is that Uber and Lyft came back to Austin with no concessions after throwing a hissy fit and leaving. That tells me that they saw something that scared them and they needed to squelch it before it escaped to other cities.
Edit: I stand corrected. The state legislature overrode the Austin laws. (Side: Wish I could put an overstrike through my comment.)
Make no mistake, this is 1990's Microsoft levels of predatory behavior. It is nothing to be praised.
They came back when legislature said "Actually you don't need to do that."
I'd hardly characterize it as a hissy fit.
Uber: I don't wanna do that! Uber: stomps feet Uber: goes home Uber: Bribes Texas state into passing laws to force Austin to accept them.
