I have a bachelors degree in electrical engineering and work experience in hardware design and in the back of my mind I've always known this to be true, but this is the first time in my life I've ever heard anyone say this explicitly. EE pedagogy is badly broken in places.
> EE pedagogy is badly broken in places. Generally, the biggest problem with math, physics and chemistry is that if you miss just one lesson (no matter if you physically miss it, or in worst case miss out understanding a concept for a couple minutes), you can easily end up "left behind" for years . With history, arts, languages, a number of computer science topics or most of biology you can either skip out on a certa…
Why do I get a sneaking suspicion that few in the machinery of education want this, as it is a fast-track to continuous accountability?

This is why 4-20 mA is a common signaling standard in industrial automation. 4 mA means zero and 20 mA means one. 0 mA means broken transmitter !
That's one reason, but the big one is that it makes it easy to remote-power the sensors. It gives them a 4mA budget to Do Their Thing even when outputting a zero.

> Some military trucks are designed the opposite way on purpose - because they’d rather have no brakes and be able to move than be stuck on the battlefield. Do you have any details on that? Or a source I could read? I'm pretty curious now. I drove trucks in the military - specifically, FMTV, HEMTT, HMMWV, and 5 tons. None of them had the reverse brakes you describe.
The deuce/half air-over-hydraulic brakes fail open (loss of air pressure leaves you with hydraulic brakes alone, loss of hydraulic leaves you with no brakes at all). However, there is a failure mode that leaves the brakes full on if the air cylinder jams. At the time it was an acceptable trade-off; later military vehicles have more in common with trucks than tanks, I suspect.

As another EE, I had the opposite experience. Voltage drops due to wire resistance and transmission losses were drilled into our heads at any possible opportunity.
Difference between focusing on digital vs analog, maybe? As another EE, I vaguely recall this being pounded into us more in power systems than any of my digital electronics courses.

Are you suggesting I'm doing worse on Google Captchas because I consider pedestrian crossing lights as a form of traffic lights but Americans don't?
Possibly. I think people in the US strongly associate "traffic" with cars and don't generally think of the crosswalk indicators as "traffic lights".
If you asked for “signal lights” I could see it. But not traffic.

There is one subtle difference between automatic transmissions and manual ones and that is the manual one will allow a shift into a lower gear even when engine damage is likely. An automatic one will not, and will hold the current gear until car speed falls within shifting range. Ask me how I know :)
Yeah, newer ones can be too smart for your own good (but not theirs) - older ones had no problem with you slamming it into reverse or park at freeway speeds - ask me how I know!
This of course meant the entire cars safety and stability control systems, ABS and traction control were all disabled. It drove like a tank.
The fix, obviously, was to replace the brake booster primer pump (hybrid car). It had worn enough to no longer recalibrate. Still perfectly functional, and would have kept working for a long time, bit it wouldn't quite meet the factory expected parameters so it failed it's test.
