If IIHS is more strict in their testing, why did the Smart receive higher scores from IIHS than from NHTSA? Didn't they only give it 4/5 stars for driver side front impact, 3/5 stars for passenger front impact, 5/5 for side impact, and 3/5 stars for roll-over likelihood? I seem to remember reading all of that right in this very forum only a few days ago.
