[Routing] Introducing "noise" when routing

[OJ W]

Depends if the route is being calculated for immediate use (satnav) or for
the future (websites)

e.g. you could imagine some popular "event" where everyone plans their route
at 9am on the day while there is no traffic, then they all follow their
routes and 2 hours later they're all sitting in a queue that couldn't have
been predicted using traffic data at the time of route planning...
