This video is an eye-opener of what damage loose items can cause in the back of a vehicle, loose items are much better stored in a lockable, safety complaint drawer unit. Cargo Barriers are essential! Imagine yourself sitting in that driver seat with no Cargo Barrier in place.
An extract from a recent Australasian Fleet Management Association (AfMA) article: When a car stops suddenly in a crash, our seat belt holds us in place, but objects inside keep moving and can impact at up to 20 times the force of gravity.

Briefcases and heavy backpacks can instantly turn into deadly weapons – severely increasing your risk of accident or even death.
