Well it is currently open and people are still driving their cars up to the doorstep of the ground, having to leave the match on 80 mins and still sit in traffic for an hour. It baffles me.
You could stay until the end, clap the players off, and lazily walk down to the tram, even waiting until the crowds have died down, get on the tram to where your car is parked, and still be closer to home than the people who left early.
When you are on the tram, you actually pass by all the people sat in their cars not moving anywhere.
