I have used Uber when I was sick.a lot around at the end of the year.
This week I had too training events where I wanted to arrive on time and without worries, and I got Uber - the prices were more expensive than they should be.
From that and this notice, I think Uber is also penalising more frequent users, from them to subsidise lower prices to attract new users.
Is it a good strategy? I often used Uber because the prices were attractive; if suddenly they are the double, I will start using more my car.
As a brief example, today I went by Uber to a training conference, the price was a bit steeper than usual; returned by tube. If the price was slightly low, I may had not take the trouble to return by tube, and Uber anecdotally would have had a little more profit.
