The US has the law backwards, to the demise of pedestrians and human life. Here pedestrians have the right of way at all times, meaning vehicles must yield to them no matter what.
This creates a false sense of security for pedestrians who are used to just stepping in front of traffic and assuming the driver sees them, or can anticipate their movement.
If the law was that vehicles had the right of way, pedestrians would have to use their eyes and ears when stepping onto vehicular roadways. Additionally, massive amounts of fuel would be saved as it's more efficient to stop a 160 lb person traveling at 3 MPH than to stop a 3,000 lb vehicle traveling at 40 MPH.
To the point of the thread; I would likely install a bullbar if I lived in Montana, Utah, Arizona, or any of the other areas where hoards of deer and elk frequently camp on the highway. These states also have a higher top speed than in Oregon.
Perhaps I'd upgrade to this:
