The Rangers legend turned pundit admits he was in favour of introducing video assistant referee technology before its arrival, but having now witnessed it in operation, he now feels the game would be better off without it.
VAR failed to intervene to award Kilmarnock a penalty in their 1-1 draw with St Johnstone on Saturday despite a blatant handball against defender Andy Considine in the box.
There was also controversary over Rangers' third goal in their 4-2 win over Motherwell over a potential offside against Fashion Sakala in the build-up while at Tannadice, referee Craig Napier was not summoned to the monitor despite awarding St Mirren a penalty when Curtis Main hit the deck when replays suggested no foul had been committed.
Hibs were also incensed over decisions made in the 3-1 defeat at Celtic Park including the red card shown to Elie Youan for a challenge on Cameron Carter-Vickers and the penalty awarded to Celtic that allowed Jota to equalise from the spot.
"I think it's been a bumpy ride everywhere," McCoist said. "I'll be honest with you, I thought it would be a great thing. I thought anything that rights a wrong must be a good thing, but I've changed my mind. It's driving me crazy. It wouldn't disappoint me if we didn't see it again.
"I'm all for goal-line technology if the ball is over the line and all that kind of stuff. But I'll tell you right now, I wouldn't be breaking my heart if I didn't see [VAR] again."
