Occasionally I'll come across a value like name=East Main Street; West 
Main Street or lanes=2; 4, almost always caused by someone merging ways 
without checking tags. It's much more common to see this happen for 
relations, where someone joins two ways that have the same tags but only 
one is part of a relation, hence breaking the relation. The existing 
tools are not sufficient for preventing or fixing these problems.
