Nit picking like a woman, are ya. Still cost less that it does to produce a tank of compressed air versus a tank of gas. Also better on the environment.
OK, let's do the math. Car's gonna cost about 10K. Economic theory would say that's approximately the value of the materials and energy that went into it. Let's say it gets the equivalent of 100 miles per gallon in terms of the energy used to fill the air tanks. And let's compare it to a car that gets 25 mpg, at a gas price of $3.00 per gallon.
To run your regular car 15,000 miles, fuel is gonna cost you $1800. In the AirPod, it'll be $450. So that's a savings of about $1350 per year. So to hit the break-even point where the AirPod is worth what it costs, you'll have to keep it for 7 1/2 years.
And remember, these values roughly represent the amount of materials and energy needed to make and operate the car. In other words, the amount of pollution created.
So there's your equation. If you own a regular sedan (actually kind of a gas guzzler) or a small pickup, and you decide to buy an AirPod for local driving, in order for the AirPod to be worth what it costs in terms of dollars, resources used, and pollution generated, youi'll have to keep and use it for 7 1/2 years.
