It's an app that creates and updates road maps, traffic and such live... It's being heralded as a facebook for drivers but it looks more like an automapper some games use..

I'm wondering what would happen if you and a bunch of friends used it while going greenlaning

Looks interesting, I'm downloading it right now and I'll have a play. We have more miles of lanes than any other county down here so well see what it s like on some of them!

I used it this weekend to get to Newark and back.
I found it crashed regularly (on my dhd) and tried to send me the long way round at every turn.

The idea looks good but until more people use it (and therefore theres more data available), I'll stick with google maps for now
