you are truly uninformed. There is so much more to the uber tech stack than this. Delivering rides efficiently, worldwide, at a scale of billions per year is not as easy as swapping out a button on google maps.
Take a smaller margin (or subsidize more, if the margin is already negative), build the driver side to be aware of and compatible with the reality that drivers are going to be driving for multiple services at once (with the exception of your seed drivers, maybe)
Now there's a reference I have not heard in a long, long time.
Google doesn't still do that, do they?

maybe you guys don't like to talk about it anymore though...
