Global Oil Disruptions and Transit/EV Alternatives

Regional retail pump spikes were influenced by maritime shipping disruptions along the Strait of Hormuz, a transit corridor handling roughly 20% of global daily petroleum throughput.

West Coast refining facilities passed inflated crude acquisition costs to local gas stations, accelerating driver adoption of public transit and electric vehicles.

Monterey-Salinas Transit and Santa Cruz Metro recorded increased ridership at single fares of $2.00 to $2.50. Simultaneously, charging session frequency surged along Highway 1 and US Route 101, supported by the Monterey Bay Plug-in Electric Vehicle Readiness Plan.
