Looks very nice. Results I get back are within expected range (for longer
routes at least).
Just one thing: are you using the maxspeed tag? When I try some routes within
town limits I get unusually fast routes. Problem is that I can't make too long
routes, but a length of 3.9 km in 3 min while crossing 6 roundabouts is too
fast. Even if you take 1 minute extra for rounding errors it is well above the
maxspeed tag of 50.

And I see that the coordinates in the permalink are not significant enough.
See my test route,
<http://mkhasanov.sandbox.cloudmade.com/directions?lat=51.3271&lon=5.988&zoom=14&layers=B000FTFTT&travel_mode=car&waypoints=5.9736448,51.3389468,6.0023605,51.3201158>
which results in a permalink of
<http://mkhasanov.sandbox.cloudmade.com/directions?lat=51.3271&lon=5.988&zoom=14&layers=B000FTFTT&travel_mode=car&waypoints=5.97,51.34,6,51.32>
which is way off, especially at point A (and it can't calculate a route for
that link).
