What is the most important safety feature in a vehicle that's helps in crashes?

The most important safety feature in a vehicle that helps during crashes is the airbag system. Airbags deploy rapidly upon impact to cushion and protect occupants from severe injuries by preventing them from colliding with hard surfaces inside the vehicle. They work in conjunction with seat belts, which are essential for keeping passengers securely in place during a crash. Together, these features significantly reduce the risk of serious injury or death in accidents.
