THE SMART CAR MAY BE LITTLE, but it gets high marks for safety:

The Smart ForTwo, the twin-seat micro that’s so small that two can fit in a single parking space, earned the top rating in front- and side-impact crash tests. It was rated “acceptable” for whiplash protection in rear-end crashes, the agency says.

There’s an important caveat: While the frontal tests do a good job of replicating a crash against a fixed object, there is no overcoming the laws of physics when it comes to crashes against larger, heavier vehicles such as SUVs and big pickups.

Still, it’s possible to design small cars that are surprisingly safe.
