Text: While consumer activists pump for another technological fix--smart air bags that can adjust their behavior to the stature of front-seat passengers--more and more of us (perhaps influenced in part by mandatory seat-belt laws in 49 states) are squandering those 2.97 precious seconds and buckling up.
Entailment: Instead of trying to develop new air bag technology we're buckling our seat belts.
Contradiction: We want improved air bag technology because seat belts are a nuisance.
