The bottleneck IMO has always been the lights at Gate 1 where cars are stopped for what appears to be around 30 mins after the final whistle to allow pedestrians a safe passage across the road. This initiative is looking to eliminate this need and personally, I am all for it.
It's nothing like 30 minutes. Even if there are two people in every car, there will still be more pedestrians than people in cars wanting to use gate 1. Why give priority to those in cars? And if those pedestrians are going to car parks on Briscoe Lane and Bradford Road, they may now leave early because by the time they get to their cars, those let out from the stadium car parks will have gummed up the roads. Maybe it is a cunning plan to get more people paying to park at the ground. And so much for encouraging people onto public transport.
