Shouldn't this be an easy think to prove/disprove by just measuring the electricity used to charge the car over time? If my car required 15-20% more gas each year, it would be pretty obvious by simply keeping an eye on the amount of money I spend on gas.

No.

Imagine the batteries that are like a gas tank that shrinks over time.

My assertion is that (for example) a car starts out with a 30 gallon tank that shrinks over time. When the car is new, it's engineered to be "empty" when the tank is half full.

It'll take the same 15 gallons to refill on the first day as it does a few years down the road when the tank has actually shrunk to be 15 gallons in size.

Yep, you are right. I was thinking of it in terms of efficiency and not capacity.
