No offence but I think it is pointless. There is no algorithm which 
can be applied to all car parks in the world and not producing at 
least a dozen of ridiculously placed icons. IMHO placing a node that 
will be drawn as an icon is twice as good as automagic script that 
counts the position above the area.

1. The icon will be always in the most reasonable place because 
human beings know better.
2. Nodes can be, someday, exported as POIs and it will be easier to 
find a node-parking rather than area-parking.

These are my 2 cents.
