You are driving a 2WD car. Doesn't matter if it's FWD or RWD. Your car has only an open differential. You get stuck in muck or sand with one wheel spinning, losing power to the wheel that still has traction. What do you do?
 
If I can't go forward, I go back.
Normally a car will not instantly get entirly stuck. Even if you can only move 6" you can use the movment back and forth to gain momentom and make some progress.

Nothing. You don't even have a floornmat. And there's no scrap wood or similar at your disposal.

Naw, your passenger side drive wheel dug itself into a deep pocket. You can't back out. Rocking is a no go. Come on, you can do it. You just have to find a way to give your powerless drive wheel some power.
 
I have been stuck multiple times, always found a way out. The real key is having the sense to know when you're going to dig yourself in before it happens, stop, and figure out what to do next. Too many hypotheticals, but I would first drop that tire pressure really low and then look for something other than sand to put under those tires. Like seashells. Rocks. Wood. Floormats.

Not the same, but probably the worst for me. I got my CTS-V stuck in a parking lot near my house after a snow storm. It was parked there and I wasn't home, a foot was dropped and they were trying to plow the lot, mine was the only car in the lot. Under the snow was a layer of icy snow that the plow did not remove.

So here I am with low tread 285 series summer tires, enough off idle torque to pull a house, no salt on hand. And a slight grade. It pulled off the parking space but quickly stopped moving at all afterwards. I tried chiseling with my shovel turned upside down to get a clear patch under a tire (posi), but the height of the car and width of the tire made that a problem. Manual trans, I left the car in first gear. The tires were turning at idle. I got out and tried to push the car with the wheels spinning. No good, it's so slippery I could not push. Nothing in the trunk. I didn't want to ruin a floor mat. Tried several ideas. So I shut it off and walked home, I filled two five gallon buckets with scalding hot water and used it to clear a major tire path. Once that was done I was good to go.

The plow guys probably had a good laugh. I flew out of the parking lot sideways. I needed enough momentum to get up the road and around to my house.
 
Apply brake while slowly giving it gas. Sounds counterproductive but might just limit the loss and help the tire with traction. I have done this on a F250 that was in some slick mud. However I'm not sure what type of differential is in it.
 
I buried my ( now stolen ) 2wd S-10 in mud on our farm. I called my wife to bring me lumber and a shovel.

I kept thinking of all those WWII documentaries of GI's digging stuck stuff out of mud. At least no one was shooting me.

A few hours of misery and it was free.

Actually, what you do is floor the gas and apply the brakes until the freely spinning wheels is being slowed down and the wheel with grip gets power. That should be enough to get the car going either forward or backward.

Like this?

Interesting, but what about traction control? The nice thing about FWD is that you can turn the steering wheel and the different angle might help you get enough traction to get out.

This did sorta happen to me during the winter, didn't move the car for a couple weeks after a few snowstorms and some of the snow eventually turned into ice under my front tires. One side just spun. As I was near home, I just used several gallon jugs of hot water to melt the ice til I could actually move the car.
 
Applying the brake will let you control to a degree how much power goes to the wheel with grip. Obviously you can't do this for a prolonged effort, or you will overheat a brake and maybe cause other damage, but it's a neat trick that often works.
