For the hundredth time, highway=motorway does NOT indicate a road's importance in the network! Quoting Joseph RP from earlier, "the freeway section of the 93 Business loop is only tagged [as] a motorway for its physical characteristic rather than its importance, and would be a primary road itself if it weren't built up to freeway standards between I 11 and VM [Veterans Memorial] Drive." That's why I tagged with highway:motorway=primary. If you really wanted to, you could ditch highway=motorway entirely and replace it with motorway=yes (and highway=primary), but I don't recommend doing this until the community reaches a consensus (Spoiler alert: it hasn't—yet).
