The local news has carried this story for some time, with many local firms threatening to leave Nottingham before this plan is implemented. The major Boots factory has over 200 parking spaces, Experian 100+ .. they are seriously unimpressed. The city council has also redeveloped brown field sites into plush new offices (now leased by Mercedes, Audi, BMW showrooms & some solicitor firms) which they sold with "ample parking" as a big plus point - little did these firms realise that those spaces would soon become a tax liability.
As for the local tram, it only serves a small number of areas and the Conservative county council (who took over at the recent local elections) pulled the plug on their £20m+ investment to help extend the network. Plus, the City Council rejected plans for a park & ride scheme along one of the busiest routes into the city (that the tram does not serve). So, we have no apparent link between schemes - stop using your car or we'll charge you but will offer no alternative "joined-up" scheme for public transport. Buses here are expensive (it costs over £2 to get to my local shops which are only 3 miles away!), cycle paths are often covered in broken glass so cyclists use the roads (including a dual-carriageway) and my nearest tram stop is 10 miles away. But, the local section of the A46 is being upgraded to a dual-carriageway at massive cost - at least we'll be able to migrate out of the area faster...
