Different circumstances, but those specific Grab drivers can go penetrate themselves. (side note: I like and occasionally use Grab, Uber, & Go-Jek, but any company that gets big enough will have some bad apples in its barrel).
As a general note for those on this thread who either explicitly or implicitly approve of mob violence: My home country also went through a period of mob violence. History does not look kindly on the perpetrators of said violence or their supporters.
Different circumstances, but pretty much same end result.
