automatic rerouting

[Martin Kolman]

• OPTIONAL
• initiate rerouting when current position is outside of a given corridor around the track
• first alert that rerouting will commence through espeak: "rerouting in 10 seconds <dramatic pause> tap screen to cancel"
• what algorithm should be used to accurately determine if the current position is inside the corridor or not ?
  • bitmap/True-False array grid ?
  • simplify the track ?
  • test segments of the track, so every n seconds the whole track is tested ?
  • test only the segment to the next point ?

My thoughts:

• Don't bother with warning ... just when car slides from the route tell "Rerouting" and continue on new route.
• I guess the last one: when the car is more than n meters from the current segment (or the current one and two neighboring segments), reroute.

Of course, offline rerouting (#32) is probably a prerequisite of this issue.
