  Clearly you don't live in the US! It's not about "need", it's about Profit.  Here, extra fees are a sign of a company that is doing well and and they can charge extras fees and make a fatter profit; and they can get away with it because they usually dominate their market.  Lesson 101 for a Harvard MBA.

How large of a field of crops would you need to power one car?  I suspect a few solar panels is easier, you only need about 1kW to charge most EVs.  Also, not competing between your food and fuel demands is good.

Many EVs will charge down to about 100V, so with the minimum J1772 rate of 6A it could be as low as 600W, though effificency likely poor due to baseline draw of whatever car systems are  powerd on during charging.
Of course at a pinch you could feed directly into the HV battery to charge at lower rates....

   If you're concerned about SHTF scenarios then get a Deuce and a Half. That's a 2 1/2 ton (off road cargo capacity) US military truck to some of you. They're diesel but will run on any liquid that will vaporize and burn and they use a mechanical fuel pump so they will run without a battery and they can be push started.  They do have glow plugs but they're generally not required for starting.  They are designed from the beginning to be a multi-fuel vehicle that can be started and operated without a battery and their are NO computers or other solid state electronics in them. Also keep in mind that jet fuel, diesel fuel, vegetable oil use motor oil, and used transmission fluid will all store longer than gasoline and the Deuce and a Half will run very well on any of them. And it might also be helpful that these have three axles and are six-wheel drive!  And, with a snorkel kit, they can operated completely underwater!

  But MPG is not their strong suit!

The metal car body would provide quite a lot of protection. Especially if it was switched off at the time.

Quite a lot of plastic panels on modern cars, especially EVs, to save weight...

I am not an expert on solar, but according to a Forbes article a 1 kW solar system produces 750-850 kWh annually for average installation in North America. So charging Tesla Model 3 from 20% to 80% would take a whopping 2-3 weeks on average depending on battery option.
