Ignoring the fact that I usually ignore it in a futile and childish attempt to not give in to The Man, why do some indoor car parks here have signs saying "forward parking only".
Most of the companies I worked for had a policy of which you park backing up so you don't reverse into the open traffic. Much safer as people are more concentrated when they arrive rather than when they leave and have to reverse.
Lots of women park indoors..and we all know how rubbish they are at reversing into a spot. Thus, to prevent further damages to the parking structure and fellow parkers, they've implemented this general rule.
Not just soot. The wall can be damaged by opening tailgate. Oh and damage your tailgate too. Not to mention its safer/easier to reverse out a bay than into it. Many a parking ding is caused by misjudged reversing.
Of course it totally ignores the fact that with most cars having front wheel steering only, reversing in is often a lot easier than going in nose first.
How are you going to damage the wall by opening the tailgate? If you are driving this, maybe but otherwise I don't think so?
It is not safer/easier, it is more difficult in fact. As I said, many companies with huge number of fleet cars have rules to only park with backing up because less screw-ups are happening compared to backing up when you exit.
It's not a bad rule for the parking company but it is a bad rule for you.
I know, because I did it in my Espace. Basically, any car with a flat bum with single piece tailgate that opens out further than the rear bumper is susceptible. And it might not be the tailgate itself, but the items that come out of tailgates. Bicycles, buggies etc. If you think it's impractical, it's worth noting I have about 2 feet of space between the bumper and the wall if my tailgate touches the wall.
Actually, it kinda depends on the layout/design of the carpark itself. In smaller, tighter, semi-lit underground carparks in some residences, it's easier to reverse out. I know, because I tried it in mine (I'd prefer to reverse in than out personally), as has the wife and the neighbour - we all agree it's easier to reverse out than in.
Which in Switzerland it seems, that they're designed by midgets, driving tiny midget cars who have no conecpt of spatial awarness and safety standards.
