They just have a different method. Plenty still have winches. But not every truck needs a winch unless you're on a real hardcore trail.
Go to youtube. Over 1000 vids of newb off road drivers getting stuck in thick mud, not soft mud. What is the first thing they do? Go straight to pulling eachother out with chains and winches. Noone even gives a thought to a little shovel time or some 4x4 wood chunks. I've even seen people wait for a track hoe to pull their $55,000 truck out of somthing that 1 hour of digging could have fixed.
Sometimes a dozen scoops with a shovel and some boards is all the truck needs to get out on it's own. Moving the truck around with a hilift or lifting your wheels and placing boards under the truck are extremely good ways to get unstuck. In my experience, plenty of heavier trucks have become stuck not even axle deep.
Or at least a little effort like that changes a 10,000 pound winch force to something easy and safer like 6-8000. And often I have nothing to connect a winch onto. Sometimes connecting to another truck just pulls that truck in. Digging and hilift methods are quiker than digging a hole and burying my spare tire. Pull palls and giant boat anchors are out of the question. Too expensive or heavy.
I think the Europeans are defaulting to a safer less harmful method of recovery. While we just default towards pulling as hard as we can and tearing up our trucks.
Used to be that way myself. In a hurry to get back on the move. But now, taking extra time to ensure an easy dent free,lesser force recovery is part of the fun of off roading.
When I was into Jeeps I would often go straight for my winch. Now that I'm in fullsize trucks, pulling with a full 15,000 pounds of force is scary and dangerous. Listening to a Warn that large start to groan is not a warm fuzzy feeling. I'd rather just do a little digging than remove chunks of shrapnel from someones skull.
