is that a 60mph speed limit or 60mph traffic speed? I ride on busy shoulderless 4-lane arterials with a limit of 45mph, where the fastest cars probably go 55. I don't take the lane (allowing cars to pass in the same lane). I voted for not bike friendly, though its far from bike-hostile and I rarely have close calls.

Asking whether such a road is "bike friendly" is obviously just trying to make a point - "friendly" is strictly a relative term (read: comparison), and an arterial obviously isn't going to be friendlier than a residential road.
