Assuming plans stay on track, in 2018 a high-speed train will race between San Francisco and Los Angeles in three hours for two-thirds the price of a plane ticket. Until then, is it smarter to fly or to drive? We compared car and jetliner travel time, cost, greenhouse gas emissions, and risk of death from a crash. The flying time includes travel to and from the airport and average waiting time, and driving cost and emissions assume a driver and a passenger in the car. For more detail on how we got our numbers, see below.
