I don't care much for infrastructure that is separate from cars, unless it is completely separate. What I've seen in the USA is a sidewalk of sorts that is a few metres away from the road, but with driveways and access roads that cross the path without stop signs. The infrastructure I've seen in Amsterdam offered better, but not complete separation. (And again the awareness thing.) The one bicycle-car collision I was closest to (my friend was in front and was hit) was on this sort of bike path. His quick reaction put him on the hood of a truck instead of into the grill. As for helmet as oppression, I heard noise like that about 20 years ago. Damn gubmint! Next thing they'll take our guns!
