I have several options, but in the morning my priority is not missing my train! When I leave, it's dark, so there is no scenery; and the roads are pretty empty, so safety is pretty much up to me; and I rarely leave early enough to have "extra" time, so I rarely think of taking a scenic detour.

In the afternoon/evening, I do try to change it around a bit, but I usually end up taking the same route every day anyway; things to do when I get home, no time to burn.
