I'd rather not have a built in tip as a customer. I don't want to tip someone who doesn't do their job well. I want to tip someone who does an exceptional job, and I may even tip them exceptionally.

Granted I've never used a service like Uber, so I can't directly understand where you're coming from.

You're supposed to tip everyone unless they treated you like garbage. People who accept tips don't make a living wage without them.

IIRC, Uber solves this by letting you rate people after each ride. People who have less than (4? 4.5?) stars get kicked off the service, so if you rate them a 1 then you probably won't see them again. So, in theory, you should only get rides from people who deserve a tip.
