        "question": "What are the ground transportation options in San Diego?",
        "answer": "San Diego International Airport sits just three miles from downtown, making ground transportation straightforward. The Metropolitan Transit System Route 992 bus connects the airport to the Santa Fe Depot transit hub downtown in about fifteen minutes and is the most affordable option. Taxis and ride-share services like Uber and Lyft are extremely popular due to the short distance, typically taking ten to fifteen minutes and costing a modest fare, making them the most commonly used option. Car rentals are available at the consolidated Rental Car Center, accessible via a free shuttle from the terminals, and are practical given San Diego's sprawling layout and limited rail coverage. The Trolley light rail system does not directly serve the airport but connects from downtown to many parts of the city and region. Shared shuttles offer a budget-friendly alternative for solo travelers heading to hotels."
