Having been in London, and having been in, like, the United States, I don't think an appropriate zone can be created with American sprawl.

And having done Lyft Line more than a few times, our current implementation of rideshare fucking sucks, too. You save like $2 and you're halfway home and then the driver suddenly makes a 90 degree turn and sends you squirreling 15 minutes into the Hollywood Hills and by the time you're there whoever fucked up your ride has decided they're not hungry anymore so now you're on Fairfax somewhere and the driver is lost and Lyft's GPS and his phone GPS are saying different things and if you hadn't been a cheap prick attempting to save two dollars you would have been home half an hour ago.

And then there's the times that you pick up someone on their way to the emergency room. And allow me to share the fact that someone taking Lyft Line to the emergency room is not only having a shitty week, they're also contagious.

These are all great ideas, but the implementations tend to suck.
