What’s more frustrating than having paid a premium to own an all-wheel-drive vehicle, and still getting stuck? Spinning all four wheels in either snow or mud is maddening, and you could often get free if just one or two of the wheels could get some purchase.
For this problem a simple, low-tech device exists: The Trac-Grabber Traction Device. It’s portable, relatively quick and easy to install and looks quite effective:
The Trac-Grabber is sold in two-packs and four-packs, in both standard and XL sizes, the latter for oversized off-road tires.
This product should be a case study for first-year Industrial Design students: What useful item could you make out of webbing straps, a D-ring, some Velcro and a chunk of rubber? I call this good design.
