Is this the worst thought out congestion reducing scheme ever?
I'm a big supporter of the reduction in car trips, but any system has to be fair and work for everyone, not just businesses. This is daft, it's going to get passed right on to people in employment, while other car users will not be affected at all. What'll happen is firms will reduce parking spaces (the number of which are usually enforced by planning anyway), but still drive to work and park in public spaces. Silly.
Far better to just increase fuel duty if you want to stop people using the car. When the oil price went up, less people drove. It's been proven to work, why not just do that?
