Crucially, this distribution of border points is agnostic of routing speed profiles. It’s based only on whether a road is passable or not. This means the same set of clusters and border points can be used for all car routing profiles (default, shortest, fuel-efficient) and all bicycle profiles (default, prefer flat terrain, etc.). Only the travel time/cost values of the shortcuts between these points change based on the profile. This is a massive factor in keeping storage down – map data only increased by about 0.5% per profile to store this HH-Routing structure!，更多细节参见PDF资料
Ultimately, based on the latest video and the limited reports so far, it’s still far from clear how this costly incident happened. A friendly-fire kill involving a longer-range weapon would be more believable, but the within-visual-range nature of this engagement is bizarre, to say the least.，详情可参考新收录的资料
