One thing to keep in mind when designing buying organizers, in the event of a front end crash, the driver may need some space in the back of the cab to survive the crash. Also, anything stored in the back seat could become a projectile if not properly secured and the front seats only provide minimal protection against those objects. Realize it is a remote chance, but still exist and can occur suddenly.
Just coming home on Sunday we saw a car that had just flipped over the barrier cables and skidded across on-coming traffic. Somehow, it appears to have missed oncoming traffic but we have no idea how.
