I recall this was suggested many years ago, but for some reason it did not fly. Maybe it is because it was too complicated to find out under which circumstances (in which jurisdictions) white lines had which meaning? Maybe we should not map the lines physically, but according to their legal meaning, something like (shorter tags would be chosen): divider that cannot be crossed (legally), divider that can be crossed legally, divider that can be crossed but only for turning left not for u-turns, etc. Cheers Martin
