I think some of you are missing the point here. This access issue is a red herring and you need to think outside the box to use that awful expression.
It works like this IMO, you don't need easy access for cars to the actual ground just to the city centre. The city centre is your car park, it seems very logical to me.
Why do some people suddenly feel that 3000 cars need to parked right next to the ground? They can't do that at BV and never would be able to yet we all seem to think BV is ok. Ditto NM which is out on a limb for most and is poorly serviced by public transport whilst I suspect there will be nowhere near enough car parking spaces provided near the site. Thornes was not that different to Balne lane in that you wouldn't have been able to park next to the stadium.
The walk from the Northgate area is not that much more of a walk than some of us make to get to BV but a hell of a lot nicer. Also because it's in virtually in the town centre then virtually every bus in WMDC terminates within 15 minutes of the place. For once it actually makes public transport look the best option which has to be a plus these days.
In it's own way it's quite cutting edge and hugely accessible to those who don't drive or can't because they fancy a drink, it is quite honestly the definition of a community stadium. Stadiums like this are the norm in France where car parking is non existent.
Finally I don't get this flooding bit some are talking about, I believe the ability to build storm drains etc has existed for decades maybe longer
It's not ideal but what is. However I don't see the point in getting hung up on the detail when for now it's little more than a rumour.
