Security Floating Deployable System for Cars

I am used to observing the things around me exploring places that most people don’t notice, and then designing products to solve problems and provide convenience for a small number of people in need. Floods have been frequent in arid places like northern China recently. Fortunately, due to the good level of rescue, there have been almost no casualties. But there have been property losses, so countless vehicles have been damaged. So I thought of designing a product that would allow people to protect their vehicles and themselves trapped in the vehicles during floods. Users need to place it around the vehicle, and when not in use it will fold at the bottom of the car without affecting the normal driving of the car.
