Economics makes assumptions about rational behavior, marginal value, scarcity, and other purely psychological characteristics.

It's still economics no matter what assumptions get used or not used in a particular application of economics. And these aren't purely psychological characteristics.

How does marginal value apply to gravity, for example? Will a star profit less by acquiring more mass per unit? Gravity doesn't work that way.

So are you claiming that economics because of my argument above, and unlike any other science, should be applicable to the entirety of all reality? I already specified the circumstances under which it applies.

As long as you have multiple parties with preferences, goods/services of value with respect to those preferences, and the ability to trade or seize, you have economics.

What parties with preference are there? There's just reality. There's no sense of goods and services to trade or seize.

Trying to apply such economic assumptions to biology results in a gross misinterpretation of nature.

The economic assumptions I mentioned earlier apply whether you consider them economic or not.

It'd be $400/mo since you're doubling the cost of the car.

I think it would come out basically even, especially if maintenance cost are lower or the car lasts longer than a comparable gas vehicle.

The big unknown with electric cars is that battery pack. I gather that's roughly a quarter to a third of the cost of the Tesla presently. Maybe the "Gigafactory" will knock that down a lot.

I'm building a house now and am even looking to avoid steel in the concrete.

I'm not an expert, but the steel is protected from corrosion in most forms of concrete due to the mildly alkaline chemistry of the concrete. And if you throw on sacrificial metal, you can keep that steel corrosion-free indefinitely.

That's a lot of traveling. Ignoring time value, the $15k difference in price buys you about 160k miles of travel (at $3.75 per gallon).

I doubt most people put 160k miles on a car before they get rid of it. So for them, lifetime costs of the Hyundai would be cheaper than that of the Tesla even if the Tesla had zero energy cost per mile driven.

Comment Profit before subsidy? (Score 1) 247

Glancing here, I gather the new vehicle will probably be able to qualify for a $7500 subsidy from the US government. What bothers me is whether Tesla can produce that car in the absence of the subsidy? A reliance on temporary subsidies for profit would explain why there has been calls to turn Tesla into solely a battery manufacturer.
