This is spot on. Cricket has similar rules for catches close to the ground, in that the umpire makes a soft call that must be proven 100% wrong. Like VAR, they regularly overturn without 100% evidence.Just on this point, they do. Any of the posters on here who regularly watch rugby will tell you that there are incidents in matches and the video ref/on field ref manage to make plenty of controversial, and inconsistent calls. Even cricket isn't immune, with stuff like contentious claimed catches and the use of technology to decide if there have been edges.
It's not just football where VAR doesn't run smoothly. Whoever deals with the incidents, whether on or off the field, you are still at the mercy of an individuals opinion. There will still be inconsistency across the board. There will still be plenty of controversial moments where teams feel hard done by.
Similarly, there were a good few years in which India refused to use technology as they felt 'ball tracker' was wrong, so their games didn't use it. Couldn't believe they were given a choice.
