Consequently, the relative speed between a striking and struck vehicle required to deploy the airbag in a real-world crash can be much higher than an equivalent barrier crash. Because airbag sensors measure deceleration, the vehicle speed is not a good indicator of whether an airbag should be deployed.
Airbag deployment happens with the same speed and force every time. Airbag devices cannot gauge their degree of deployment to match varying forces of impact. It is an all-or-nothing deployment.
Airbags deploy at speeds up to 320 km/h (200 mph; 89 m/s) and in some cases exert tremendous force on the windshield. Occupants can impact the airbag just 50 ms after initial deployment. [9] Depending on vehicle design, airbag deployment and/or occupant impact into the airbag may increase forces on the windshield, dramatically in some cases.
In the US 49/563.5 regulatory framework, Event data recorder is defined as a . a device or function in a vehicle that records the vehicle's dynamic time-series data during the time period just prior to a crash event (e.g., vehicle speed vs. time) or during a crash event (e.g., delta-V vs. time), intended for retrieval after the crash event.

The passenger-side airbag was a "dual-stage" airbag, meaning that the impact sensors determined the force used to deploy the airbag based on the severity of the impact. Of the original fleet of Chevrolets, virtually all were eventually disposed of except one, which is currently fully restored.

Airbag on a Bell OH-58 Kiowa helicopter. Crashworthiness is the ability of a structure to protect its occupants during an impact. This is commonly tested when investigating the safety of aircraft and vehicles. Different criteria are used to figure out how safe a structure is in a crash, depending on the type of impact and the vehicle involved.
