Comment Re:I need to see more (Score 1) 711

Why does it matter how long you let the wheel spin up? Isn't the spinning wheel in this scenario just storing energy that was output by the drive over time? And extracting power from the wheel causes the wheel to slow down? You need the thruster to be applying enough force to make up for what you're extracting from the wheel, off the energy you're pulling out of the wheel, and if the one is less than the other then you're not perpetual, right?

Comment Some of this sounds perfectly rational (Score 1) 125

Ignoring messages (read: popups) "when going to close a web page"? Of course I'm going to ignore those--I don't think I've ever seen a legitimate security warning when I was trying to close a page, but I have seen a lot of sleazy attempts to prevent me from leaving someone's web site. What action is it that I'm performing by closing the web page that I might be making a mistake with? What alternative path is being suggested to me there, just leave the page up forever?

In the other direction, paying attention to warnings "after interacting with a web site" makes sense--if the site is lying to me about its identity or doing sleazy things with javascript, telling me about that lets me know that I should probably trust it less and at least think twice about providing sensitive information to it or downloading executables from it.

Comment Re:Driving yes, but charging? (Score 1) 990

I spend less of my time charging my EV than you spend filling your car's gas tank.

I arrive home, plug in and leave it. I don't have to stand by the car waiting for it to fill. In the morning, I unplug it. A few seconds to plug in and another few seconds to unplug. How long do you spend standing by your car at the gas station?

And that's irrelevant for PEOPLE IN APARTMENTS, which is where the thread started and what the grandparent's point about "time spent at the gas station" was relevant to.

The one that irked me (to the point that I remember it, anyway) was...that one Highlander movie with Adrian Paul that made it into theaters. I was a big fan of the TV series already; trailers had the villain doing a bunch of magic that adolescent-me thought would make him a unique threat to be faced. Movie comes out, nothing like that to be seen. The villain's most threatening move is hiding a dagger up his sleeve. Half the TV episodes had more impressive opponents.

Comment Re:Seems this topic is stuck in the roundabout. (Score 1) 364

I'm not sure that's actually true. If we were talking about a situation that occurs (for a given driver) ten times a day, I would agree that repeated practice would get you to the point that you would reflexively do the same thing you did the last hundred times....but "pedestrian teleported in front of my car and my only choice to avoid him is to drive off a cliff" isn't something that most people are ever going to encounter, much less encounter often enough to make automatic a response that matches what they'd do with careful consideration.

It doesn't matter what you say you'd do when confronted with the situation when you're sitting in philosophy 101.

Comment Re:Interesting idea (Score 5, Insightful) 400

I feel like there's an "agency" aspect to this that I haven't seen mentioned yet. Even if, overall, people are safer on transport they don't control (buses, airplanes), the fact that they have some control over the risk when they drive makes them feel like it's less risky even if it really isn't. "Those 1,000 car deaths were probably all distracted idiots or maniacs or drunks--I'm a better driver than that."

Comment Distrust of the source (Score 5, Insightful) 282

When I see a commercial make a claim about a problem, and the solution to that problem just happens to be "Buy our new product!".....yes, I would say that the proposed solution tends to make me view the claim about the problem more skeptically. That seems totally rational to me.

I don't see why this would be any different. If it sounds like someone is pushing the need for tighter (or looser) gun regulations, it's reasonable to question if they've cherry-picked their statistics about the problem to support their case.

Maybe f they'd had one source give a totally neutral statement about a problem, and then a different source suggest a solution, and managed to prevent the subjects from realizing that the experimenters were responsible for both statements...
