Works great, with a few flaws

Ive been using the application in France and it has really helped me get around, including staying off the toll roads. The biggest problem Ive encountered is that in areas with a lot of roads in close proximity (as happens a lot in Paris), the location marker jumps to a different road and the app then tries to reroute me back to the road it just thought I was on. It seems like a bit of hysteresis could help here.
