I have no real choice. My commute is all rural, and this is a very old settlement area, the roads follow old trading paths between towns. A bunch of radials out from each town to the others around. If you want to get from one place to another between towns, there's really only one way to go. If I want to take an alternate route, at the least it adds 3 or 4 miles to an 11 mile commute.

There is no bicycle infrastructure around here, and few of the roads even have paved shoulders. It's 2 lane roads, zero shoulder, 50+ MPH roads.

I don't really have any trouble with traffic though. Drivers are pretty good and the amount of traffic on a route never really comes into the equation.
