The Green Plan was indeed introduced as an encouragement to use public transport as a cheaper and easier option than driving. However, the public transport options have never been there consistently. There used to be many more buses running on matchdays to satisfy this perceived demand, but over the years they've been cut back to quite frankly ridiculous levels, so much so that to me it seems like they've lost sight of the initial reason it was implemented. It takes my dad over an hour now to get back home, whereas in the car it would take 15 minutes. The train situation has also been an embarrassment.
The council I expect have the 'final say' on whether parking restrictions are implemented, and they have agreed a threshold of 10k in an official capacity. However, they are consulting someone who stands to gain financially on whether the threshold will be met and this third party has been wrong roughly 85-90% of the time this season. Quite frankly it's disgraceful incompetence. Wasps couldn't give a flying fuck about whether residents in Holbrooks can have space for visitors, and the fact you continue to peddle this garbage makes you complicit in the lie.
In short, stop talking bollocks.
