And the odd thing was that this wasn't the only spot where it wanted me to do this on this trip! Also, I used a previous destination that I had entered the prior week, and that trip didn't have the jogs.

I had picked the second choice on the 3 routes screen. I wonder if this is a "minimize" highway route, so it gets you off the highway wherever possible?

I picked the second choice because I thought it was taking me down Highway M6 (based on the zoomed out previews), but I was wrong. I will pay closer attention when I pick the route next time.
