No kidding. Driving GoJek on weekdays to hit 30 points, in my experience, need 12-15 hours. Maybe others need less as each day's drive is different for each person. It is madness. At least need 25 trips per day to get $400++ in nett fares. But incentives can be attained daily. Today fail to get 30 points, tomorrow try again. But still got consolation 23 points and nett fares around $300.
For Grab, I also need at least 330 gems per week to see $308 incentives a week. That's like also 23-28 trips a weekday on Grab. And the hours for me is also 12-15 hours a day. On Grab my gross fares usually average around $300 and on weekends may see $400 or even the rare $500, and I am talking about just gross fares on Grab. And there were a couple of Sundays where I really panicked to get the last gem by midnight just to get the incentive payout, and all or nothing scenario for the week's efforts.
So for now, and for me, GoJek gives me better earnings for roughly the same amount of effort. Other brothers here may have different and better driving experience (lesser hours more earnings) but for me it has mostly been 12-15 hours if want to see better earnings.
