When route-planning my cycle trip to work, Google insists I should take an expressway which would not only be illegal but also pretty suicidal. I both edited the expressway and used the feedback form, but a month later nothing has changed. (Luckily Open Street Map gets it right.) What are your experiences with Googles latest addition of crowd-sourcing?
