I put a request to my local council on the cost of installation, cost of policing, and expected revenue for the parking meters they were proposing to install. Essentially their business plan. The answer was staggering; they said they did not have the information.
The meters were duly installed on the stated date. SIX WEEKS LATER all the meters were changed for solar powered ones where you have to enter your vehicle registration. I should ask the cost of that operation.
