I do not like extra laws that are unnecessary but I would like to see a law, stating that information re parking fines etc had to be visible at a sensible height, well lit and in the same place everywhere, so at the entrance to the car park, and if it is the carpark of a hotel or restaurant, another sign by the door you go in. Then it could be seen as fair, making sure that customers or visitors to a hospital could park, and put off those who misuse the system. However I consider that many places now either, do not police their own car parks, and are not interested in warning you about the charges, or are actively either making money themselves from it or the greedy carparking firms are charging well over the odds and it is to their advantage to have poor signs, badly situated and poorly lit. It would be good to start a campaign about this and take pictures of such signs and places and write to the local paper about them. This would warn people of deliberately difficult to see places, and make cafes etc aware of the consequences of making things difficult unnecessarily.
On occasions I have been to speak to the managers in such places, telling them if I think the notice is badly placed etc.Sometimes I get a good result, where signs are moved or made more obvious, but on other occasions I have returned to tell them that I no longer go there due to their parking restrictions, and reminding them that I have previously brought them quite a bit of business , which they will no longer receive and that I shall encourage friends and family to also go elsewhere, if it appears to be sharp practise.
We should all be fair and not misuse their parking spaces, but that goes two ways.
