Yesterday, our adventure made me wonder a lot about Mother Nature and human decisions.
If we take Saxton, we do the San Francisco Street Car route:

Here is AI TMI: "Russian Hill and Nob Hill are two adjacent, iconic summits forming part of a continuous north-south topographic ridge radiating through northeastern San Francisco. Despite sharing a strict urban grid layout that forces roads directly up extreme slopes, each hill features distinct geographic heights, grade changes, and physical workarounds to handle the dramatic drop to the San Francisco Bay.

Topographic Overview
Feature
Nob Hill Russian Hill
Peak Elevation ~351 feet (107 meters) ~358 feet (109 meters)
Peak Location Jones St & Sacramento St Jones St & Vallejo St / Green St
Maximum Slope Grade ~24.8% (Jones St) 31.5% (Filbert St)
Primary Slope Direction Slopes down toward downtown (East/South) Slopes down toward the northern waterfront
Nob Hill Topography
Nob Hill serves as the high anchor directly bordering downtown and the Financial District.
Wikipedia
The Crest: The summit acts as a relatively high, compact plateau before dropping sharply on all sides.
Southern & Eastern Slopes: The descent toward Union Square and Chinatown features long, continuous, intense inclines. This terrain is famously conquered by the San Francisco Cable Car system, specifically the California Street line.
The "Tendernob": The southwestern slope transitions into a gentler, gradual grade as it meets the flatter Tenderloin valley floor.

Russian Hill Topography
Located immediately north of Nob Hill, Russian Hill presents a highly fractured, irregular terrain.
Wikipedia
The Crest: The peak features a dual summit pocket around Vallejo and Green Streets.
Extreme Steepness: Because the streets follow a rigid grid over severe drops, Russian Hill contains some of the steepest navigable urban roads in the Western Hemisphere. Filbert Street between Jones and Leavenworth hits a punishing 31.5% grade.
Pedestrian Workarounds: Due to the severe topography, many streets are impassable for cars. Planners bloc
