This is the status update for busy area. >50% and above
Means you are qualified for incentive if you Ar above 88%, ba >50% (which u are 100%), rating >4.7, cr <10%

couldn't answer all, so i'll answer which ones i can

the map shows the demand over past 10-15minutes, i think. it's delayed a bit, not actual real-time.
for the drop of riders, almost everyone got the same impression as yours. it's due to early Ramadhan (where most ppl balik kampung want to do 1st day fasting at home). plus, it's 2-week school holidays. by now, you should realized fewer traffic jams.

if you're fulfilled the Grab Pro requirements, then you'll be consider to be in it. (minimum 88% AR, 10% CR, 4.70 DR). this must be reached by Sunday 11.59PM every week. if not reached, then you're on Grab Flexi instead.

I would like to ask, if my car is modify like im have changed my front bumper to an aftermarket bumper? Can i still use my car for grab? Fyi my car is saga flx

Maybe what u said is true, Grab try weed out some underperforming driver and ask them switch over another side or force them to become fare driver (Grab earn 20% commission instead subsidize them incentive)

Seriously the promo code churn up some demand, if not demand would be a lot lesser in this ramadan month.

The issue with Promo code is i don't know what is their SOP, credit back to wallet by how many days? there are so many promo code around there and it is pain in arse to follow 1 by 1

If Gold member couldn't get the 5x points, this card going to hide inside drawer and i'm switching back to Petron
