I don't get it. Not joking.
Imagine you're standing outside in the cold. It's snowing. You have to get somewhere. You need a ride. Of course more people want a ride when it's cold and snowing. So you wait and wait.
That's what surge pricing is about. When there aren't enough cars to meet demand, the price goes up. Price-conscious people take public transit or a fixed-price cab. And presumably more drivers head over to where there's a greater demand, so they can get rides, and make more money. I guess if Uber really wanted to do it right, they'd let people bid on the price. So you could get a ride at the normal price. But only if someone wanted to provide a ride at that price. That would be the total VRM solution.
Surge pricing isn't a great name for what it is, a market.
