People buy smaller cars because fuel is expensive, and repairs for the most popular small cars are cheaper since material costs predominate. In the US, fuel is inexpensive due to a lack of fuel taxes, food and other house home goods are sold in large containers leading to a cost savings if you can buy them and your big car can transport them, and labor is relatively expensive so repair costs flatten out when comparing car models. Lastly roads are huge so no one feels a pinch driving a big SUV. That’s basically it, the economics of the US make it reasonable to drive a big car.
