Where do you go that doesn't have Lyft, but has Uber?
I travel regularly and it is very rare not to have Lyft available. Virtually any city with >250k has both from my experience, although that could just be where I travel, I don't know.
Kansas City, MO has both, but wait times have been much higher for Lyft when compared to Uber. At least that’s been my experience. I only try to use Lyft.
