Who the hell would want to drive within a kilometer of the MCG when there's an event on? There are trains and trams right outside and they are sooooooo much quicker than cars.
Honestly, that stadium is filled every weekend for half the year. People should know better.
I live right near the MCG and a decent number of people still drive in. I'm not sure why though since the city council makes a fortune by doing the rounds 2 hours in to a game and ticketing everyone without a parking permit (which is a lot of people) and the number of vehicle break-ins is pretty high too.
They are paying money to own these vehicles, therefore they must use these vehicles for everything possible.
For these people, riding public transport is more abhorrent than having their car broken into, or to receive a parking fine for parking in someone else’s rightful carpark.
