Wrong. You said it yourself: radar technology is so sensitive that they have to dial it down, otherwise they're swamped by false positives. If a giant bomb-dropping machine traveling at Mach 2 can pretend to be a sparrow flying over some forest, it's already a win. So it's a huge positive when fighting someone even with that kind of technology. When fighting someone whose AA system is a guy holding an AK-47, it is 100% useless. Until we get to active camouflage.

It's the same transition television had when going from SD to HD. Makeup, lighting, and set design all had to change because the increased clarity of HD exposed the flaws. It's like turning on the bright lights in the bar at 2am. Raw and ugly.

As filmmakers learn to work with HDR, films will look better. Same as when color hit the market. And sound. And the transition to film itself.

Important people get preferential treatment all the time. I've got a nice chunk of change stored at my bank. Ever since I put it there, my customer service calls have been diverted directly to Executive Customer Service. I don't even have to do anything. My phone number is linked to my account so my calls go straight there, picked up by Frank or Veronica in Texas before the third ring. I rarely need to call them but it's nice not to sit in a queue like a schmuck listening to hold music warble in and out.

And what's the deal with hold music? Why is it always distorted and fading in and out? Shouldn't we be able to fix that by now?

Touchscreens are terrible in cars because you have to look at the screen to see where to touch. Knobs, levers, switches, and buttons can be operated by touch while keeping visual focus on the road. It might take a couple weeks to learn a new vehicle but you can learn to operate it by feel.

You can have electronic communication on an isolated network. And there are plenty of ways to input data accurately with error checking. Add CRC to the input. If they don't match, find the error(s). Or dual/triple/quad entry so that it's only accepted if the fields match. Like when you're creating a password for a new account. Or print a QR code and scan it on the isolated system. You can pack a lot of data and error correction into QR codes.

Of course, this all assumes that the input is legitimate.

They did if they were expecting a standard yellow light, then it changed red in 2.5 seconds instead of the federal minimum of 3 seconds and slammed on the brakes to avoid running the red light. And 3 seconds is the minimum. It needs to be even longer on fast roads.

Generally, the yellow light should last a bit more than 1 second per 10 miles per hour. A 45mph road should have a yellow light that lasts about 5 seconds. But it's not required to be 5 seconds. It can be as low as 3 seconds. And many cities got caught going below even that minimum requirement at intersections with cameras. So people who drive that road know they have to stop fast on a yellow even if they can't do it safely. They have to balance the will get a ticket or might get rear ended.

> It is not known how the US government has determined that North Korea is the culprit

Of course it's known. The same way they established that Iraq had chemical weapons. The method is known as "because we say so".

Are you joking? I thought it was well established that there were chemical weapons in Iraq we just only found weapons designed by us, built by Europeans in factories in Iraq. And therefore the US didn't trumpet their achievements. In the case of Iraqi chemical weapons, the US established that Iraq had chemical weapons not because they said so but because Western countries had all the receipts.
