A PUBG player protected his Bronco at all costs, and it was rather entertaining. While most of us would be pretty angry if someone scratched or damaged our car, I don't think we would whip out a grenade.
But PUBG is a battle to the death, and you'll throw a grenade at anyone that looks at your car, let alone scratches it. Now, it seems like there is only one enemy in the line of sight of Riphz, but there is one more in the hills. Whipping around, he locked on his prey and let loose.
Up on a hill, he sees an enemy player hiding behind his Bronco, and our protagonist does the right thing. Instead of shooting through the car or even driving up to him and throwing another grenade, he goes for the headshot. Lining up the shot through the window, Riphz times it well and takes out the second player.
Both cars were untouched in the chaos which is what really matters.
