Can I put an air cushion in the car?

Car air mattress can't go on the road for the following reasons: 1. It is a violation of traffic regulations that a car uses an inflatable bed while the vehicle is running and is checked by the traffic police; 2. It is unsafe to use an inflatable bed when driving, because the inflatable bed is elastic, and it is easy to shake from side to side when driving, which is easy to make the body lose balance; 3. The vehicle will have great inertia when braking, so it is not recommended to buy or use it while driving.
