Careful what you wish for...........
Problem is, once you get rid of them (or even drastically cut back their numbers) there
WILL be chaos..... Not death on the streets and rabid frothing at mouth type chaos, but word will get around (via the local rag and sites like this) that West Berks is a free for all and cars will be pretty much abandoned outside shops, on pavements, in loading bays, in disabled bays, in bus stops , on double yellow lines, outside school gates, and it wouldn't be too long before some would be demanding they come back .... (I'm not joking!!

)
There are a fair number of shop owners who currently say that the wardens are 'scaring away trade'. Well that may or may not be true but I'd say that's more just an easy excuse to point at when the main factor determining low numbers of customers through the door is the harsh economy and lack of pennies in the pocket....
Imagine you're a shop owner in this 'park for free town', needing daily delivery but your supplier constantly has problems because the nearest loading areas are always full of cars. How long would suppliers put up with it if it's constantly impacting on their deliveries elsewhere... Shop owner would want something done... The police certainly wouldn't be interested and won't ever have parking put back under their wing... Who would they turn to?? Who they gonna call? (Ghostbusters don't do parking enforcement either....)
If I remember rightly (and I do...

...) Maidenhead went for several months without any form of parking enforcement in 2006. The council took over the powers from the police (who dropped it like a hot potato) but the council decided not to go to the bother of employing wardens and had a few months of 'Live & Let Live'. Chaos ensued...
This archived Maidenhead forum rant gives an idea (feel the anger of Mr Shopkeeper...
