Passage Summary: Minivans have great safety stats on the road, but they don't actually perform better in lab crashes. This suggests the cars aren't safer; it's just that the people who buy minivans tend to be safer drivers.

Conclusion: The superior safety record of minivans is likely due to the cautious nature of their drivers rather than the design of the vehicles.

Reasoning: While minivans have fewer real-world injuries per vehicle, controlled crash tests show they do not protect occupants better than other similar-sized vehicles.

Analysis: The argument identifies a discrepancy between real-world data and laboratory results, then attributes the real-world success to the 'low-risk' driver. To strengthen this, we want to see more evidence that the driver is the relevant variable. Look for an answer that shows what happens when the driver variable changes—perhaps showing that when high-risk drivers use minivans, the safety record plummets. It turns out that hauling a soccer team might actually encourage more careful driving than cruising in a sports car.
