Before turning the key for San Antonio, Texas, out of Austin, Texas, run through the pre-trip checklist: registration card in the glovebox, current insurance card on your phone, working SunPass or E-ZPass transponder for the electronic toll plazas along Interstate 35, and a printed backup of the destination address in case GPS reception drops. The locked itinerary measures 140 km (87 miles) with an optimistic estimate of 1h 20m if cruise control sits steadily within the posted limit. Pulling out of Austin, the capital of Texas and a fast-growing tech corridor, the road eventually delivers you to San Antonio, the home of the Alamo and seventh-largest US city. Schedule departure outside the morning rush window and pack a thermos of coffee to skip an unscheduled stop in the first hundred miles. Budget around $11.68 just for the pump (12.7 liters / 3.4 gallons of regular unleaded) plus headroom for tolls. Outbound reimbursement at $0.43/km equals $60.20 cleared to the driver.
