Luggage inside the car
Driving with luggage inside the car cabin without being secured is a huge risk for all people being in the car.
In the event of an accident at 37 mph (60 kmh), every item which goes free in the car multiplies by 56 its weight causing lots of damages to those in the car. i.e. a carryon of 22 lb. (10 kg) free in the back seats will impact to the driver’s body like as being a bull (1,100 lb. – 500 kg).
Another clear example is an innocent pen. They will become a knife thrown to your back if it’s not in a compartment.
