Hello! Allow me to help!
Your question: An engineer of Volkswagen America spent three and a half hours on a Greyhound bus to experience the vast distances Americans travel in their automobiles and to try to understand why Americans treat their automobiles as rolling extensions of their living rooms. What kind of data did the engineer collect
Your answer: He collected data about people driving their automobiles, and why they seem to use them like a moving living room.
Why is my answer correct? Good question! Allow me to explain: Deprived from the text. "to experience the vast distances Americans travel in their automobiles and to try to understand why Americans treat their automobiles as rolling extensions of their living rooms." proves this to be accurate.
Hope this helps! UwU
