Parking should always be set up so those first in get to be the first to leave. Otherwise what's the incentive to arrive early? You get a mad rush nearer kck-off to try and be as late as possible so you can get out first.
Reminds me of Brandon on a Saturday night in the seventies - esp for Stox. Jammed in bumper- and door-to-door. No chance of leaving early unless you were on the edge rows.
