they're not mate, and that's why until I see a plan which offers potential solutions to these issues and an outline on how it's all going to be funded I'll remain very sceptical.
I hope they're forthcoming because it's my preferred option as well.
The parking argument is bogus though. There are other larger city centre grounds (think 55,000 at St James Park, 32,000 at Bramall Lane, 80,000 in Cardiff). Look at aerial views of St James Park and see how much on site parking there is.
I read something once about Newcastle, it was a study about how people got to the game. Can't find it now which is annoying, but it basically said that 30% or thereabouts travel to the game by car - and there is an average 2.5 people per car. At BPA, for a full house that would translate to 3000 cars, but they wouldn't be concentrated around the stadium area - they would be dispersed and many would use city centre car parks. There would also be businesses, schools etc who would cash in by opening car parks - and there would also be some street parking.
A city centre ground is by default close to the main train station, it is by default on every bus route in the city. There would be park and ride, coach services from outlying areas, and let's not forget, the ground would be within walking distance of many residential areas including Earlsdon, Spon End, parts of Coundon, Radford, Cheylesmore, Hillfields etc. Traffic could also disperse easily, because by using city centre parking those people would enter and exit the city centre via the 9 different ring road exits. I just don't see how it would an issue at all.
