More specifically I'm describing a feature I see at MapQuest web service.
http://open.mapquestapi.com/guidance/#advancedoptions
*direction*
"Provides an initial compass direction of travel to favor when
generating the route.
If the |direction < 0|, then no direction is favored.
If the |direction >= 0|, then the calculated route will attempt to
follow the given direction at the beginning of the route.
This is useful for real-time GPS guided applications in which the user
is already traveling in a certain direction and would like to ensure
that the returned route starts heading in a similar direction."

Hi Peter,
I would like to ask if it's possible to include the vehicle bearing
(as taken from gps) at the routing calculations?
Let me give an example of the problem which is important for mobile
routing.
Let's assume that we are with a car in a 2-way road facing right and
we want to perform routing with 'start' our position and 'end' a point
far behind (left) on the road.
Now GH (as it is a 2-way road) indicates a straight path connecting
the 2 points, i.e. in reality to turn around.
That may be possible with bike or foot, but we're using a car, we
cannot simply turn around.
The logical path would seem to move forward till the next turn in
order to be able to go back at your destination.
So is it somehow possible to use also the car bearing at our calculations?
