There are the occasional wrong-way drivers on the bike paths.

A while ago I saw about 20 feet of guard rail mangled along one of the Eugene bike paths. Hit by something much larger than a bicycle. I seem to have misplaced the photo. Surely it was hit by something that wasn't supposed to be on the bike path. Yet, it was also in a place that would be exceedingly hard to get to.
Just yesterday I saw a full sized police car driving down a bike path. Headed towards a bike bridge, then under an overpass. A rather large vehicle for the place it was at.
