Not disagreeing with this, but unfortunately there are also large sections of society that would never use public transport, even if it picked them up at their front door and took them directly and efficiently to their destination at a fraction of the cost of the car.
On the money with this.
Vast swathes of society are addicted to their car. The convenience of leaving your front door to the front step of your destination is too appealing for some and I include myself in that. I live in an expanding village that has a mainline train station 10 minutes away and a bus service to the neighbouring towns. I've never used the latter, I have to say - the car is quicker. No need for timetables, waiting for the bus, needing change to board, nor the walk to and from bus stops. I walk to the local shops but one resident I've seen near where I live has never walked any further than where her car is parked, often to drive around the corner.
The club need to be very careful and honest about the new stadium development and exactly how many people will continue to drive to the stadium as it will be an easy stick to beat them with either prior to the build or not long after its finished. There won't be a utopian shift to public transport with 90% of attendees arriving by bus, train, unicycle etc as so many in the habit of using their cars will continue to do so. Incentives will be the way to discourage traffic around it. Money off the park-and-ride bus if you need to drive to the stadium, % off food and drink if you show a valid Oxford Parkway train ticket, concentrate match day parking in areas where park-and-ride options are available and which won't annoy residents.
I personally would take public transport to the stadium but I can fully understand why a resident in Wantage, Witney, Watlington, Wallingford* etc wouldn't. The journey there and back just isn't feasible.
