I saw some nice fields that could have been safer than the highway but it's a PIC call. If there is a lot of traffic going for a highway over a nice field can be a poor choice. BUT it worked out OK so he did well. If I had to offer a critique of his landing it would be that he did not hold the centerline but drifted right to the hard shoulder before touching down. Poles etc. can ruin your day big time.
