Of course I know that I have to do the "quoted" in my style-file. But to 
do exactly this it would be good to have some tags deleted beforehand / 
ignore list where I can list all tags I want to be ignored (like 
motorcar=no; motorcycle=no; psv=no;...)
The problem as we know is that action rules are only matched on one way, 
so putting the "Access" rules as action rules might not work if there 
are other rules enacted on the same way!

My action rules are already 3000 lines long to catch as many 
possibilities as possible. Adding access into this means 3000³ lines 
only for action rules in the lines file and would crazily slowing down 
mkgmap.
