A new system was created to study car crashes and prevent them. It looks at different situations before crashes happen, like how the cars were moving and what caused the crash. The goal is to help make cars safer and prevent accidents. The system found 37 common scenarios that lead to crashes, with around 5.9 million crashes each year costing $120 billion and causing 2.8 million years of lost life. This information can help make cars and roads safer for everyone.
