Commercial for Greyhound bus lines; an older man interviews Greyhound passengers outside the buses, asking how Greyhound helps with the gas shortage; reasons range from comparisons to gas mileage on a car to gas use per person, and finally: “well, the Greyhound bus is my only car!”; announcer ends with “join America’s biggest share of the ride club!” and the trademark sign, “Go Greyhound and leave the driving to us.”
