I doubt that the difference will be that big. If the price of oil goes up, electricity will get more expensive too, especially if you consider the electric grid needs to be completely overhauled (at great cost) to allow for mass electric charging.
I'm guessing they already have the designs for the higher capacity pack, so they can make sure it's compatible. With newer technology, between different manufacturers, that may not be so easy.
Why not a hybrid then ? Put your 30HP engine under the hood, and cut the battery pack in half. Charge it at home for 150 mile range, and run the ICE for longer trips.
In addition to the problems you mentioned, a swappable battery pack would also make it hard to improve the technology. New tech may not be compatible with old car electronics and form factors.
First of all there is no such thing as a standardized connector for more than fifty or so KW. Sorry.
Tesla could help design one, together with other electric car manufacturers. If you can use each other's charging stations, it would help solve the chicken/egg problem of electric cars, and benefit everybody involved.
Does the 230 mile range include electricity consumed by the A/C system ? In any case, going slower will increase A/C power consumption for the same distance.
Why not get a beagleboard, then ? It's already available, has better documentation, and an active group of developers. Or a beaglebone, or one of several other cheap processor boards that are out there.
Especially if you're interested in hooking up other peripherals, and don't need 1080p video output, other boards are probably a better choice.
And the web server you can just run on a regular PC. If you have a dozen PCs, chances are that at least one of them is on 24/7 anyway.
I was just joking of course, but the target audience isn't your average computer programmer. A computer programmer would just buy a regular computer, or, more likely, already own several.
The GISTEMP graph has an upward trend in your graph.
The HADCRUT data doesn't cover the Arctic, which is the area of the earth that has shown the most warming in recent years. Arguably, the HADCRUT data underestimates the global temperature.
Without the raw numbers, and precise details on how they were reconciled, this isn't science - it's just politics.
Science is built around dealing with incomplete data. Anyway, you can fairly easily verify the numbers in a little while by comparing them to the latest CO2 measurements in the atmosphere.

Even though weather is not climate, the large amount of broken weather records is certainly an indication that the climate is shifting.
There's is evidence this has happened before in the end-Permian extinction.
Urmm.. that's exactly what we've been doing for the last 100 years.
What you're stating is the broken window fallacy.

All those things are bad for the economy, which is the reason that the governments haven't actually done anything so far.
True but irrelevant. It's like saying it's okay to flood cities with water, because fish depend on it.
If you go slower, the trip will take longer, and therefore the A/C needs to be on longer, and thus consume more electricity.

That number sounds very low. Do you have a source ?

Gasoline is also damn safe, despite common portrayal in Hollywood movies of cars blowing up at the slightest provocation.
TFA mentions that competitors are already using a standard connector:

Still, at the current rate it takes an hour for a 300 mile recharge. That's quite a long time to be waiting.
Doesn't sound smart to equip these vehicles with a proprietary connector. Why not have a standardized connector, and sell more vehicles ?
Why would have a big asteroid in orbit make any of those things easier ?
And how much fuel would it cost to capture the sucker ?

Or maybe they think the target audience is particularly gullible.
Suppose you manage to carve a nice big chunk of ore from an asteroid, how do you safely land it on earth ?

So, why isn't there a decent trend line drawn into the graph ?
Here's the same data, with trend lines, and some discussion about the error bars and statistical significance:
