That's good for muck where there is a measure of 'suction' to overcome. It's not really needed for a snowbank.
BTW, the running start ... really isn't. You're supposed to inch forward until the strap becomes tight but not stretched. At that point, the recovery vehicle guns it. The stretch of the strap will provide a measure of momentum to overcome the suction of being stuck in muck.
A running start will only guarantee a broken strap, potential damage to both vehicles and possible injury to anyone within reach of the strap.
... or so I've heard ... I've never experimented to find out.![]()
