The fact that my friends still pile up at Chick-Fil-A makes me want to disagree. No matter how principled people claim to be, they always end up back with what they know and like, in this case Uber.
Not true, Uber can be 40-60% cheaper. I've stopped taking public transit in the Bay Area because of Uber, I don't think I could do that with Lyft alone. Is there another competitor with cheaper pricing?
I don't know about the US, but in India, Ola offers cheaper prices than Uber (about 30 - 60%) and people are switching to it. Uber hasn't been deleted, but it's losing customers (at least the ones using cab services regularly) to Ola.
