Nothing is preventing a business from building parking spaces though. It's just getting rid of the requirement to do so. It's essentially a free-market approach.
I think there are bigger issues wherever you are, in that there doesn't seem to be (enforced) parking laws. I see this pretty frequently in the Balkans, for instance.
The issue is basically that a lot of places people have this idea that, just because they own a car, they are entitled to a cheap/free place to park it. That type of incentive just leads to more and more people buying cars (and expecting a cheap place to park them) so it just makes the problem worse.
I can't check at the moment, but that sounds like something 'Simply Perfection' would be capable of.
It's essentially an addon specifically for tweaking the appearance of gnome stuff.
