We already have robotic area denial. It's called sentry guns. Of course, we also have anti-sniper robots. Hooray arms race.

You're a brain in a jar, right?

Golly man, how much of a judgmental asshole are you? Not only that, but you're also a moron. The issue is height. I'm two meters tall, and most of my height is in my trunk.

Because people who want to drive a sedan don't want to pull a trailer. But for a pickup it's a complete non-issue because even if you're using the bed, you can still put a generator on one of those hitch-mount cargo platforms.

Nissan and Toyota don't make mid-size trucks. They finally started making half-ton trucks, but they abandoned the mid-size truck market as well and only make normal-sized trucks and itty bitty trucks. And that's why the disappearance of the Ranger, the last mid-size truck, is so frustrating.

Some of us are too large to sleep in anything smaller than a long-bed pickup truck. I'm two meters tall, there's no Subaru in which I won't be cramped lying down. As well, you certainly can't haul a sheet of plywood in one, but that won't even tax an electric pickup. Some appliances will fit in a Forester, but few will fit in any other Subaru.

I have a car and a truck though. Both diesel. Car gets 30 mpg free way real-world and has enough room for a mutant like me.

That's not what happened, because now there are no trucks which do precisely what the Ranger did, which is to say be a light truck with room for fat people, even if they are tall. So now you need a mid-sized (half-ton) truck to serve that purpose.

The good news is that the mileage on the half-ton trucks is getting better...

As a person, that sort of thing is a problem. As an international corporation, you have choices as to where you do business.

Actually, I'm not even talking about the grip safety. I own a Kimber, and I know about it, but it's not what I mean. You can hold the pistol tight enough to depress the grip safety and still have FTFs because you're not holding it tight enough.

If you have a transflective, decently high-resolution display, you can display barcodes on your screen and the scanner can read them. Most loyalty cards have barcodes even if they have magstrips.

That's OK, this is fixed in Kitkat.

"We at Sears hold substantial real estate with high retail value. So we're going to turn it into something that is best located where nobody else wants to go, since that's where taxes and traffic are lowest."

Wait, what?

That depends on what kind of firearm it is, and how it is operated, e.g. recoil vs. gas.

What I find interesting is how some firearms don't operate correctly if you don't hold them correctly. Tightening your grip will stop FTF in some 1911s.

The fact that an ugly piece of plastic does give the middle finger to the government is what makes it an important political statement.

Sure, 3d printing will revolutionize explosives. But it's also going to revolutionize reactive armor.
