First topic message reminder :
iv just been reading some thing iv thought was right for some time now, that is that the average space to park a car is just not wide enough to allow a car to be parked side by side with others parked, opening the door often results in the door banging the door of the next car and not leaving the driver or passenger much room to get out or in for that matter
often resulting in scratch's to the paint work
a study by Halfords that I read said that despite the average car growing in size as manufacturers strive to offer more interior space crash protection and comfort the department for Transport rules governing car park space size have remained the same since 1994
the width of cars has increased by an average of 16% over the same period making the average car 2" wider than the 1.80mm (5ft.11") minimum parking space,thats 40mm smaller than a Ford Focus and making it incapable of accommodating a B.M.W.3 Series measuring over two metres (6ft.7")
but car park operators looking to maximise visitor volumes and revenue, there is little incentive for them to exceed the recommended minimum size requirements, the research found that Supermarkets were reported as the worst offenders by 38% of drivers, followed by shopping centres 29% and railway stations 18%
no wonder some times tempers get a little frayed when a driver thinks some one has deliberately parked inconsiderately, well now we know
is it the same in the U.S.A. and else were I wonder, as for here in the U.K. and as a driver I would like to know when the parking spot minimum size is to be updated to accommodate the modern car size and save car paint work and driver frustration.
W.D.40 
and I even use it for fishing,a spray of that on your reel helps keep your line floating on the surface when fishing surface baits 
but then again like you said this thread is about car parking space's ,well W.D.40 Could be used to help slip your car out of a tight spot if those parking space's get any narrower so to speak.
Gets easier after several times.
