Final answer:
Airbags in cars improve vehicle stability and protect the driver from airbag injuries by reducing excessive steering and deploying upon impact to minimize serious injuries to the passengers.
Step-by-step explanation:
Airbags in cars help protect the driver from airbag injuries and improve vehicle stability. They work by reducing excessive steering and deploying upon impact to minimize serious injuries to the passengers. The momentum change is the same for an occupant whether an airbag is deployed or not, but the force that brings the occupant to a stop will be much less if it acts over a larger time. This is why cars today have parts that can crumple or collapse in the event of an accident, as it increases the time of impact and reduces the force on the car and its occupants.
