In other sports, such as American Football, I think the idea of "clear and obvious error" or "indisputable evidence" as it's called there makes sense and often works out. I'm not really sure it makes sense in football. So many things like red card offenses or fouls in the box are too subjective, and refs can just hide behind "clear and obvious errors" because there isn't always a very set rules on what constitutes a foul. I think removing the "clear and obvious error" would hopefully make VAR a bit better
