While the pay is not much, it is possible to make preety good connections driving for GRAB. A friend of mine drove for Grab/Uber for a couple of years before he met with a fellow driver who started hiring him to ferry customers from the airport to Airbnb hostels. He also gave cheap all day private tours of KL and Melaka to the angmohs for extra money.

Fast forward, and that friend of mine has been given the opportunity to buy a few rooms in a KL condo to do the same airbnb business by that initial friend. Now making in excess of RM8k a month without needing to drive as much as Grab. On peak months, easily can hit RM14k a month without driving a lot also.
