Since for many people it is sort of common to drive off of paved roadways and onto grass or dirt/gravel roads. Many parking lots at parks or roadside attractions have grass parking areas. So you must only drive a 4x4 vehicle to allow you to absolutely drive on paved roads and maybe unpaved surfaces too. But for parts of my driving life I was able to survive just fine without a 4x4. Just a front wheel drive car!!!!!! It was fun when I did have a 4x4 pickup. Being able to go about anywhere at anytime was fun. But not absolutely necessary. I was a little more selective and careful with the 2 wheel drive car.
Sorry, your four wheel drive argument fails in exactly the same way.
I've never owned a 4WD car, and probably never will. Except for one
really, really unusual exception (an interesting story I'll relate
below) I've never come close to needing it. And that's despite tens of
thousands of miles traveling in small 2WD cars towing our camping
trailer, including on gravel roads. On many occasions (like the annual
county fair, or the rural home of one of my best friends) I've driven
and parked on grass. More to the point, we get snow and ice all the time
in winter. I've got over 50 winters' experience driving in it and never
needed 4WD to negotiate it.
There are people who need it - like, good friends of mine who live atop
a very steep hill in a snowy city. But as with clipless, most people
never get any real benefit from 4WD, but they cheerfully suffer the
detriments of higher initial cost, a more complex system with greater
chance of malfunction, and less gas mileage. They're victims of
advertising.

> When using shoes with cleats on the bottom you do pull backwards on the pedal as you go around the stroke. I agree you don't really pull up when riding. But you do drag your shoe along the bottom of the pedal during the pedal stroke. And you can when the back plate of the pedal is enclosed in the cleat on the bottom of the shoe. Real toe clips and straps and cleated shoes. Using toe clips with non cleated shoes and you are about certain to pull your shoe out the back of the toestrap when riding. Unless you really tightened down the strap.
There's friction between the shoe bottom and the pedal top, aided by the
lumps and bumps molded into most shoes' soles. I do pull back at the
bottom on tough hills, aided by "ankling." That's possible even with
loose straps.
One semi-famous touring personality in the 1970s was Captain Dan Henry.
In addition to lots of interesting bike tours, he did pretty amazing
roller riding demonstrations at bike conventions.
He rode in men's leather dress shoes, not even with toe clips. He
carefully sawed a shallow slot across the leather sole to accommodate
the rear edge of his quill pedal. I used my chronograph wristwatch to
confirm that he could spin about 200 rpm on the rollers.

My tale of the ONE time 4WD might have helped me:
Our yard slopes downward toward the garage. Alongside the garage were
three small ragged evergreen bushes. Despite the fact that only the
neighbors can see them, SWMBO wanted to replace them with something
prettier. I dreaded the task because it meant digging out the existing
bushes.
One day when the ground was nice and soft after a couple days rain, she
persuaded me to start - but then I had an idea. Maybe I could attach a
long chain to the car's trailer hitch and use the car to at least put
tension on the shrubs as I dug at the roots. Perhaps they'd pop out
after I severed a few roots.
I never got to find out. I backed the car onto the lawn, hooked the
chain around a shrub and the hitch, and tried to apply a little tension.
Even before the slack was taken up, the front wheels sank into the wet
lawn. I had no idea things were that soggy.
I tried the usual remedies of having people help push, rocking the car,
etc. No dice. The front wheels just sank deeper. What to do?
We do carry a basic AAA membership. It includes one free short-distance
tow per year. I decided to use it for the shortest tow ever: from my
lawn to my driveway.
A nice young guy arrived with a big flatbed truck with a cable winch.
With his truck on our driveway, he had no trouble at all winching our
car onto the pavement. Hauling 3000 pounds across wet grass was easy.
Then came the unusual part: I said to him "Say, what would you think
about using that winch to pull these shrubs out of the ground?"
"Oh, I couldn't do that without checking with my supervisor first! I'm
sure I'm only supposed to use this for official business. I mean, I
could phone him if you like, but I'd have to get his permission!"
I said "Your boss doesn't know how long it took you to pull my car free.
If you don't tell him, he'll never find out. How about $10 per bush?"
He thought for a couple seconds, then said "OK, I'll give it a try."
And it worked beautifully! The cable winch sucked each bush right out of
the ground with no trouble. I actually gave the kid $50.

Follow up: We got new neighbors about three years ago, a young couple.
The guy is muscular and macho. They decided to rip out most of the
foundation landscaping in front of the house. One large shrub gave him a
_lot_ of trouble as he dug deeper and deeper, hacking at large roots. He
had the same idea, hooking a chain to his big 4x4 pickup and alternately
trying to pull, then trying to hack some more.
With the chain hooked at ground level, he spun his 4x4 tires on his lawn
but the bush's roots held fast. After a while I suggested he attach the
chain higher on the trunk to get torque on the roots. Doing that, he was
able to pull it out.
