>Airline travel is only better than cars if you compare it to a 1-passenger car Why would you compare it with anything else? People don't actually fill their 5-8-person vehicles, almost ever, and certainly not on longer trips. I don't have any sources handy, but I'm pretty sure an airplane is significantly more fuel-efficient (which also means less CO2 output) per person for a NYC-LA trip than a gigantic pickup truck with even 2 people. Comparing air travel to a fully-occupied Prius is a ridiculous comparison, because Americans just don't ever drive that way. They drive huge trucks and SUVs and they drive them with 1, or at most, 2 people.
