Interesting. For my routes the time estimates seem to be pretty accurate, and I'm not fast at all (average maybe 12.5 mph).
The primary route it recommends for me is 9.7 miles and it estimates 53 minutes (not a bad route, but a little too busy for my tastes). My actual route is 9.2 miles and takes me 45 minutes. My wife is a little slower and 53 minutes is almost exactly what it takes her for the 9.2 mile route. I know a guy from my neighborhood who could easily do it in 35. So the time estimates on flat ground aren't bad at all.
I wonder if the estimates in your area fail because they don't take hills into account?
