Yes, for my daily commute to and from work I can take the most direct route which involves a motorway, or take a slightly longer back-road.
Both before leaving in the morning and returning in the evening, I check the motorway traffic flow on-line. Even so, I have been caught out a few times by accidents which occurred after I had commenced my journey.
