Mark, the wiki page about restrictions http://wiki.openstreetmap.org/wiki/Relation:restriction says I can put a key except with the following values/meaning: except - psv/bicycle/hgv/motorcar - The restriction does not apply to these vehicle types (more than one: except=bicycle;psv) So do you mean that mkgmap does not actually support/handle the except key in a relation restriction?
