Uber got very dominant in market share in Moscow with all its subsidized rides. I paid 200USD for 30 rides! This is not sustainable...
I think that the rating system helps at least partially to fix this exploit (if it actually is an exploit and not a fantasy).
And that's the price of Uber as well, which can go up in rush hour, but we now have Taxify as well, which I prefer because their prices are more predictable.
So when you're saying that you paid $200 for 30 rides, that seems expensive to me.
