I'm in the NYC market. I use Lyft to get around and Uber Eats to order things that could never have a business model delivering to me. To me market capture is just as bad as the original Taxi model, but even Taxis have gotten around to handling this problem. You can switch to the app in the middle of a ride and pay with the code on the back seat tv screen. The convenience factor is only there for food until another competitor enters that arena.
It's a race to the bottom and I suspect after all the hard work is said and done Uber will be the Yahoo of ride share. Tesla may very well swoop in and say "Thanks for blazing the trail"
I believe the person is referring to ‘uber cash’ as an loyalty incentive, paired with changes to the uber credit card coming next year which will only give uber cash (akin to airline miles).
