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!
Which MacBook should you buy?As of February 2026, I think the 15-inch M4 MacBook Air is the best choice for most people. It offers quiet, Pro-level power in a more portable design and at a more reasonable price point. Better yet, it's frequently on sale for under $1,000 at Amazon and Best Buy.
