In a frontal collision, the safety systems have a little more time to react because there is a crumple zone at the front of the vehicle. In the case of a side impact, just a few centimeters separate the vehicle’s occupants from the oncoming object – which means that the available reaction time is that much shorter. Side airbags, therefore, have to be activated far more quickly: a function that the pressure satellite fulfills admirably. It detects the change of pressure within the door, thereby reacting extremely quickly.
