I saw a link at Go Clipless to a post on Stuart Brown’s weblog, Angry Cyclist. The post is titled “5 road signs that don’t exist, but should”.
Above: Road signs, left to right: Glass shards ahead, No overtaking bikes, Car doors are in operation in this area.
Above: Road signs, left to right: Vehicles parked in cycle lane ahead, Now entering bicycle theft zone.
I thought it was a funny because it points out the completely different perspective that you have when you are on a bike. :) Be sure check out the original post.
