Answer 2
There are huge variations in what cars can be modified to use ethanol due to the car manufacturer and year the car was made. If car was made after 1985, ethanol should not be as corrosive as for cars made before 1985.
Higher concentration (for example E85 or fuel with 85% ethanol) will have corrosive effect on rubber, plastic and/or aluminum parts that are not designed for it. Aluminium can be protected by anodizing it which will add protective layer to it.
Smaller concentration (E5 or E10) will not affect unprotected aluminum parts at all. They might still have negative impact on unprotected rubber parts (fuel lines, injector seals etc). Fuel tanks (or the lining within) might have problems withstanding the ethanol and should be replaced with suitable tank.

Excellent explanation. Also all gasoline sold in California is 10% ethanol by statute.
Rubber is an insulator, so lightning cannot effect rubber shoes.
The polarity or charge of rubber when rubbed with the appropriate material is negative.
Negative

Ethanol can cause damage to engine parts. It can also lead to damage with seals that protect your motor because it eats away at rubber.
no
usually, positive wires have a blue rubber coating, whereas negative wires have a red rubber coating.
No, the ethanol will "eat" the rubber in the fuel lines, pump, and seals.
an electrostatic negative charge
yes the weather effect the rubber inside
No it would not because electricity does not effect rubber. Tires are rubber.
because its texture
