[GraphHopper] Why not using OSM way uid?

[Andreas Fischer]

Hi there,

I was just wondering why the OSM UIDs are not used instead of iterative
self generated non deterministic edge IDs.
Does this have any particular reason? I wanted to log the drivers data and
match them with the OSM file to have some statistics and increase prognosis
by updating average speed etc. .

Kind regards,
Andreas
