Bukit Bintang.  Once drop off, ping immediately, but mostly short trips.  After 9pm, not sure.

drive for incentive. don't care if short trip. because grabcar will still pay you the guarantee hourly rate. PJ area should be good. camp at shopping malls / LRT stations.

Today incentive play:

I dislike driving in KL city. but is also unavoidable.

Aim 1 trip per hour will do. finish the first trip then can go lepak somewhere under the tree, petrol station, etc. receive ping can do more trips is a bonus.
When reaching the following next hour then only go out to hot spot area (shopping malls, etc) to find ping request.

Use waze to navigate. Got estimated time. If nearing like 5.55PM estimated time arrival, then just drive slower on the road so that when you drop your passenger the time is 6PM and you are good for the next hour block. Because I kena before. Received ping at 5.59PM, but the entire trip (pick up until drop off) took more than an hour due to jem. burn 1 incentive block. If only the ping is 1 minute late, then incentive will count for the 6PM block.
