A lot us already knew this, but now it’s official.

Buyers choosing the smallest cars for low price and high gas mileage could be endangering themselves and their passengers, says a major auto-safety researcher.

In new crash tests, the Insurance Institute for Highway Safety rammed three automakers’ smallest cars into their midsize models. Although the small cars had passed other IIHS tests, they flunked in collisions with larger but still-fuel-efficient sedans. “The safety trade-offs are clear,” IIHS President Adrian Lund says. “There are healthier ways to save gas.”

Which is why I drive an SUV and why the worldwide campaign to demonize large vehicles is ridiculous and profoundly anti-choice.
