we humans have no maps built in (although yes we’d build a memory of a location if we visit more than once). You come up to a blind crest you slow down until you can see the other side - should be the same. Likewise for sharp corners - current autopilot just seems to go ‘oh this is the speed limit? Cool’ and then aborts through sharp corners because it can’t turn quickly enough, rather than slowing for the turn. Just doesn’t seem to properly adapt ahead of time
