If I was Uber I would love to have a competitor as callow as Lyft; they seem willing to cede whole markets up front. For me it's as weak as not internationalising your software; if you wanna downvoted for this view point that's fine btw but I stand by it!
EDIT: downvoters, Lyft has $2.01 BILLION dollars in funding... It's ridiculous to suggest they shouldn't be competing with Uber internationally!
