Yes. Well I’ve never had a problem before. They cones are put across roughly around the 90 min - full time mark. If you leave on 75-80 mins you’ll be fine. Unless they’ve changed the rules but we’ve been doing this on and off for years. My partner did it at the Newcastle game and got out fine, no traffic or traffic cones across. Left on 80 mins. Don’t hang around though, if you can get back to your car promptly and drive off immediately you’ll be fine.
