GrabShare was good if
You don't mind who was the second passenger
You don't mind another 20min extra to pickup and drop off
Most people don't like. Most of the time you tell them got a match , their best answer was Oh. At last they don't happy with the trip , driver get the low rating.
GrabShare also shown that the rider are not willing to pay extra for already a not expensive trip.( consider you getting a car and a driver reach in front you , not lrt etc )
I have once a GrabShare that drop off second passenger first and need to big u-turn at jam hour , at last customer say you should drop off me first where he was super right but I just follow system and I don't know that road much , if I drop off him first how about second passenger?
The rate of matching was low even for long trip.
Maybe no rating for GrabShare trip?
grabshares main problem is that riders fail or dont even realized that when they booked grabshare they are actually sharing the car with someone else. i still remember grab instructing drivers to tell riders that they have booked a grabshare ride and if there is a matched ride the driver will have to go and pickup the matched grabshare ride...
some riders accepted it some didnt. those who didnt straigth giove u 1 star rating thinking we are simply taking another rider on what they think is their booking...
