Wow, that's a lot of hate. I'm not sure where you're from, but you certainly aren't representing that place very well. Most "Americans" actually aren't "arrogant cocksucker"s. Unfortunately, the ones that are can be pretty vocal, not unlike yourself...

Howitzers don't fire rounds at mach 7. Also, any electronics in a smart rail gun projectile would need to withstand a pretty intense magnetic pulse.

The projectile only needs to be conductive (electromagnetic), not ferromagnetic.

You need a fuel + oxygen for something to burn. Oxygen doesn't burn by itself. In this case, it's likely that tiny fragments of metal being scraped off of the projectile are the fuel.

So it will paint a box on the image, showing you how your car lines up with anything next to it, just like reverse cameras usually do. The car could also have a range-finder built into the camera pod, or whatever, to look for and warn the driver of fast approaching vehicles in adjacent lanes. That would pretty much eliminate the need for 3d.

That must not be the case today since we haven't heard about volvos breaking any testing equipment.

The first Tesla battery swapping stations are apparently going to be opening shortly, so it will soon be an available option in at least some locations.

Surviving is not the same a living.

Emissions testing a Tesla? What emissions would those be?

That's the idea for the Model E.

Apparently the swapping station keeps track of which battery is yours. When you come back it will give you back the same battery.

there are a string of superchargers connecting the coasts, so it is possible to drive cross-country now. Though you currently don't have much choice in route.

Yes, in fact pretty much every car in existence that has AC is able to do this. All you have to do is turn off the AC, and all of the power that was being used to cool you is now instead available to move the car. Amazing, huh?

The automatically controlled clutch may be faster, but there's just something about doing it yourself that makes you feel more connected with the car, and just plain more enjoyable to drive. Plus, there's no nanny to get in the way. It would drive me crazy if I requested a shift and it refused, or if there was a noticeable delay.

I remember hearing a story once about work vans (ie: no seats in the back) having a higher tariff than passenger vans, so a company (i don't remember which automaker) was installing temporary seats that were then removed and shipped back to the factory once the vans made it into the US.
