Car safety is very important. There are many different types of car safeties that protect us in case of an accident. Drivers in the United States put more than 2,969 billion miles on their tires, but most drivers don't get their tires changed because their too expensive. 11,000 tire related accidents happen a year and around 200 people die in those accidents. For 30 years the NHTSA (National Highway Traffic Safety Administration) and the Department of Transportation have tried to make cars more safe and roads more safe to prevent less crashes. They've been improving seat belts, airbags, car sensors, etc. They've lowered the number of car crashes and deaths by car crashes immensely and is still dropping. Frontal airbags have saved 25,782 lives from 1987-2008. They've recommended that children under the age of 12 should sit in the back seat. Frontal air bags can do more harm than protect small children. Car companies run many different test over and over until they've gotten it right. There are many different things that add up to saving someone's life in a car crash, these are just a few examples.
