中文原文

优步的产品非常简洁。它在司机和乘客之间建立一个交易场所，并从车费中抽取大约 1/5 的佣金，优步服务的用户越多，便能越好的发挥作用：乘客减少了等候时间，司机更好的利用了自己的时间。

自己的译文

What Uber is doing is very simple: establishing a dealing platform for drivers and passengers on around 1/5 of commission. Its performance is proportional to the number of its customers: with the decrease of passengers’ waiting time, drivers can also enjoy more flexible times.  

经济学人原文

Its product is elegantly simple. Uber makes a market between drivers and passengers and takes a cut of about a fifth of the fare. The more people use its service, the better it functions, with lower waiting periods for passengers, and better use of drivers’ time.

注：原文用 its 是因为有上下文，这里 its = Uber’s。

原文中惊艳到自己的地方

👉中文是“简洁”，如果只翻译成simple那就是“简单”，看到经济学人原文用了elegantly simple，果然很妙。

👉cut

[N-SING: oft poss N] Someone’s cut of the profits or winnings from something, especially ones that have been obtained dishonestly, is their share.[INFORMAL]

The lawyers, of course, take their cut of the little guy's winnings.
