It can't be exploited by either team, only the officials on the pitch in conjunction with those in front of the screen can bring the use of VARS.
Not sure what your point is really in regard to delaying the game, for the gain of whatever team that might be.
Same reason players on the leading side will feign injury, to interrupt the flow and reduce the pressure. You've never seen a game where the losing side are hammering the oppositon, but then they have a long injury and the game just fizzles out?
As for who can abuse it, I'm pretty sure those paying for the service will be able to do whatever they like.
I’m pretty sure you don’t have a clue what VAR is
5 mins to go leading team being bombarded, balls into the box, bit of a shirt tug, ball to hand, slightest touch on an attacker in the box, there are many ways VAR could end a game five minutes early.
The game is only stopped if the VAR team think the wrong decision was made or if the ref needs help. Did you watch the World Cup?
Where have I contradicted this? The point is the VAR team have the ability to stop the game.
In the fact that you say players could abuse it. If anything it’s the opposite
