Uber and Careem these services are good for city like Islamabad where roads are good, wide and there is no issue of "behungam traffic". You will actually enjoy driving in that city. But in city like Lahore where half of the city main roads are dug up for Orange line project and remaining half are suffering from potholes and car breakers (speed breakers), driving with Uber or Careem for few hours will cause fatigue and you will get tired. Also the streets are so narrow here in Muhallas k Gadi tuwadi waji hi waji. So If you are a real tough guy with strong muscles and you can afford heavy maintenance cost from your pocket then consider driving with these services.
And I would recommend miser riders to develop a habit of giving tips. Giving tips to taxi drivers is a common thing in western countries. If you are getting something for so cheap then get your heart bigger and may be give a little tip to encourage them.
