I think they have some bugs: it also claims it's faster to drive from Milwaukee, WI to Lansing, MI than the adjacent Madison, WI. Furthermore, there is a section of I90, a Madison ring road, which Google Maps claims is 15 minutes from Madison city center and 5+ hours from Lansing, while this map claims it's closer to Lansing. There are similar tendrils of I196 through Holland, MI and I to Grand Rapids, MI that go to Madison (5+ hours) instead of Lansing (1-2 hours). Or maybe we're reading the map wrong? You can get to each capital any number of potentially shorter ways, but almost any location in Michigan routed to Madison will take 196, while only a few from that spot going Lansing will take that road...
