Navigation systems take account of the angles when deciding what
instructions to give. If a way splits with both
forks being nearly straight-on and with a small angle between them they
will be saying "keep left/right" and not "turn left/right".
Routing is distinct from navigation. Routing is mathematically choosing
which lines to follow. Navigation is much more than that - it
is for the human, so it's about searching for locations, giving
directions (based on the result of the "routing"), displaying maps etc.
