California → California · Interstate 5
On heavy-rain or dense-fog days the Sacramento, California, to San Francisco, California, leg routinely demands well more than the 1h 21m estimated: Interstate 5 carries known hydroplaning hot spots and reduced-visibility corridors that justify dropping to 35 mph through a few short stretches. The outbound run covers 142 km (88 miles) over varied topography between Sacramento (the capital of California and gateway to the Sierra Nevada) and San Francisco (the Northern California finance and tech hub), demanding sharper attention on mountain descents and shoulder-less curves. Before pulling out, check brake-pad wear, tire tread depth, and washer-fluid level in the reservoir. Fuel spend holds near $11.87 for the 12.9 liters (3.4 gallons) consumed. Even in adverse conditions, the flat tariff of $0.43/km guarantees the standard outbound payout of $61.06 — log any incidental costs (extra toll, mandatory meal, emergency lodging) in a separate field on the Clara receipt.
