Any feedback on Uber and Grab car business?

My friend started his Grab and Uber business at the latter part of last year. According to him there's a significant decrease on the demand for both when this year came. But nevertheless it still generate a good amount of money for them. Only the downside is that of their driver's as the incentive is not that much as before and the quota even got higher.

Well, it's very significant that more people are buying brand new cars to enroll at Uber or Grab. Meaning, there's really an income out of it.
