Car safety has more to do with safety ratings of the vehicle. Motor vehicle crashes are one of the leading causes of death in the U.S.. According to the Center for Disease Control, in 2009 more than 2.3 million adult drivers and passengers received emergency room treatment for injuries suffered in car crashes. The economic impact of vehicle crashes is also notable. The CDC noted that the lifetime costs of crash-related deaths and injuries among drivers and passengers were $70 billion in 2005.
Plus, driving safely will also have an impact on your factory warranty, extended auto warranty, if applicable, and the life of your car. If you use and abuse your car, it can possibly make your factory warranty or extended warranty invalid and it will also decrease the life expectancy of your vehicle.
