Small cars are not as safe as big cars in a crash. It's basic physics: If you put tons of metal around you, of course it's going to take the brunt of a crash. The engineers at XP Vehicles just might change that with their new small car, the Whisper. They say the Whisper "is the safest car ever designed for drivers, passengers and pedestrians." The Whisper achieves this level of safety because it's inflatable.
