In other words, virtual reality. The problem with the current VR headsets like the DK2, is you have effectively a 1080p display that fills most of your field of vision, in other words, yes - you can see the pixels and they are pretty big. The screen door effect is also pretty bad. Text is very difficult to read using the Rift DK2 unless the text is very large.

Developing very high PPI displays will be a real benefit for VR headsets. Tne next crop (the Vive/SteamVR and Oculus CV1) have better resolution (IIRC it's something like 1200 pixels vertical) and probably will have much less of a screen door effect, but the resolution really needs doubling at least for a VR headset to truly feel HD.

No, he's pointing out that people who want to kill other people for notoriety are going to do it, laws or not.

Like any other crime, there are a few people who will commit the crime regardless of any law, and there are of course many people who would never commit the crime, even if they were 100% guaranteed to get away with it. The law's deterrent effect is seen only in the third group of people: those who would commit the crime if they thought they could get away with it, but won't actually do it because of the risk of being caught and punished.

It sounds like you are arguing that the third group does not exist. If so, I think you are wrong about that.

The charging cables would have to be enormous, though, to fill (say) to a 400 mile range in less than 3 minutes. The currents and voltages required would be absurdly high. Let's say we have a 180kWh battery/capacitor we want to fill in 3 minutes (0.05 hours). The power coupling would be running to the car at 3.6 megawatts during the charge cycle. With a 11kV coupling you'd need a current of almost 330 amps, so big, thick and heavy conductors. Even if the charger was 99% efficient, you'd need to dissipate 36kW of heat energy during charging (about equivalent to the power output of a small car at wide open throttle).

Having quick charging capacitors/batteries isn't even half the challenge of making an electric car charge rapidly.

It's not that simple. A 12 volt lead acid battery won't give you a shock, for instance, even though it's capable of delivering hundreds of amps and stores a lot of energy. Your skin resistance is highly non linear. At low voltages (for example, the voltage your multimeter puts out when measuring a resistance), the resistance from one hand to the other holding the probes with dry skin is a few megohms. But as the voltage rises, there is a point where the resistance dramatically falls and much higher currents can flow. You need enough voltage to be present to result in a lethal electric shock.

Pretty much the only time spent is actually at the pumps.

Okay, let's say a smart ICE owner spends 5 minutes a week refueling his gasoline car.

The next part is, how much time does an electric car owner spend per week waiting for his car to recharge? More than 5 minutes per week, or less?

All that happened is that the NSA listened in on terrorists, as well as other nations

If that was "all that happened", there wouldn't be much controversy. But in addition that, the NSA was also extralegally collecting the phone records of tens of millions of Americans, despite repeated assurances to the public that they were not doing that.

Jesse Ventura put it rather well when he said something on the lines of "Give me Dick Cheney strapped to a folding table and a pitcher of water, and in 5 minutes I'll get him to confess to the Manson Family murders."

I think Mr. Ventura would be better served by waterboarding Cheney until Cheney agrees that waterboarding is torture.

Once that's been accomplished, there are only two interpretations: either Cheney has finally admitted the truth, in which case we have established that waterboarding is torture and therefore illegal; or Cheney was lying in order to make the waterboarding stop, in which case we have established that waterboarding is ineffective as means of extracting truthful information.

A cynical person might interpret this as suggesting that the conservative voters are motivated much less by "freedom" than by the sweet, sweet indulgence of their fear and hatred of (whichever non-majority social groups have been selected as their official scapegoats for the season).

CURRENTLY free. As a carrot to get people to various locations. When it becomes popular, it'll cease to be free, as it'll be a measurable cost to provide.

Tesla has promised that Superchargers would remain free to Tesla owners indefinitely, so if they renege on that promise to existing owners, there would likely be lawsuits.

Of course they could make charging non-free to people who buy new Teslas in the future, but given Tesla's high-end image, and the relatively low cost of providing the service, they'll probably just keep doing what they do now -- figuring out how much the average Tesla's lifetime use of the Supercharger network is likely to cost them, and bumping up each car's sale price by that amount.

I can go 500+ miles in my car, and then do it again 2 minutes later.

You can go for a ride inside your clothes dryer too, but why would you want to do something so unpleasant? Outside of a dire emergency, I can't imagine anyone wanting to do make two 6-hour trips with only a 2-minute break in between.

Here's something to try: find out how much time the average ICE car owner spends driving to gas stations, waiting in line, waiting for his car to refuel, paying for the gas, driving back, etc. Then find out how much time the average electric car owner actually spends waiting for his car to recharge. The results may surprise you.
