I agree. I think lanes=* should record the total number of marked lanes (i.e. road markings must be present to indicate the lanes). lanes=1.5 is subjective, and anything subjective should be avoided. Instead, record width=* (estimated or actual) then the onus of interpretation falls on the user, not the mapper.
