I've ridden on a lot of bike paths at the the 15 mph (more or less) speed - which is what I go on the road unless I'm sprinting. I think the driveway and intersection issues exists when you ride in the road just as much. In my town there is a stretch along a busy road that has a bike path similar to this one. I don't mind riding in traffic at all, but since it's there, I take it and bike stress-free.
