Normal Bicycling Directions a la Google

I tried the new bicycling directions at Google maps, asking for directions from Heartland Community College to an address by Landmark Mall. The directions included a u-turn onto the Constitution Trail at the college, which is kind of strange, and then proceeded east on Raab Rd., to south on the Trail, to east on College Ave. I understand taking the Constitution Trail but College Avenue seems a little risky for a bicyclist. Getting directions for biking is a nice feature to add, but it does reveal the lack of safe bike lanes throughout town.
