San Marino

Översättning på gång, här den engelska: 

Sands’s ability to absorb energy is proven useful, for example, in car racing.

Studies of ballistic shots into sand show that sand can absorb more than 85% of the energy smashed at it, the ability increasing with the speed of the projectile.

Sand barrels and sand cushions have saved lives at many race tracks. Historically, it has been a part of safety arrangements at events such as the San Marino Grand Prix, held in Italy as San Marino, with more cars than people, lacked a racing arena of its own.
