I absolutely hate tips in Lyft. I wish the service just cost 15% more. The Uber experience is just slicker. Hit a button, get in, get out, and the only impediment is rating. Tips, you have to guess amount ($1? 15%? 20%?) and it's always an extra step. I'd be 100% Lyft if they killed tips or let you opt out of tips/opt into recommended tips.

Or if they were very optional. But they feel obligatory. I wouldn't mind the ability to pay extra.

Ding ding ding! Free money usually makes people happier than no free money. I exclusively use Lyft, and talk to my drivers all the time. They also say Lyft riders are better than Uber riders. Not sure if free money plays into that, but I guess so.
