Easy answers. Chinese DVRs that ignore the "mandatory" limitations appear on the market. Or chipped players. Or homebrew tech. Only the obedient sheeple will then be screwed.
But the SSL/TLS handshake can be modified. And the modification can be detected and blocked too. That will trigger a death spiral of arms race that ends up with massive deployment of advanced steganography techniques and city-wide off-ISP mesh networks. With sneakernets as one of the additional parallel systems.
For those of us who drive cars built in this century - cars that more often have sensors, computers and storage for mileage* - these systems are troubling.
One thing to keep in mind: The cars are computers. We are hackers.
So it won't be so easy, but as long as the signals from the sensors are not fully encrypted and authenticated, they may be simulated with a $2 microcontroller - the issue here is to make the engine control unit think that the mile tracker is connected, and convince the mile tracker that the car is not moving. With full encryption, it may be easier to entirely replace the engine control electronics - or use a less hostile model of a car.
1) If it is technology, it can be hacked.
2) Everything is a form of technology.
There is a nifty thing for handling compressed gases, called a pressure regulator valve; prevents your overpressure/burst scenario. Commercially available off the shelf; ask eg. any diver. Combine with a safety valve for increased reliability. A float-gauge connected to a cutoff valve for the bladder then prevents the overspill scenario; can be also done electronically, using eg. capacitive level sensing or taking data from the existing level sensor for the fuel gauge.
So yes, it does not need more than just a little work to get it right.
Fuel dyes are added to the fuels in order to mark them as tax-exempt. Most often they are azo dyes.
Theoretically there are ways to get rid of the dyes. One possibility is to use an activated carbon. During WW2, when British avgas for war planes was dyed and there were occassional road checkpoints, the staff of the airports was routinely "borrowing" such fuel and removing the dye by pouring it through a gas mask filter.
Other possibilities are using biotechnology (see the patents related to cleaning effluent waters from manufacture/dyeing of textiles, maybe there are some bugs able to live on the water/oil boundary and eat preferentially the dye), or selective dissociation of the diazo bond with laser pulses or microwaves tuned to its absorption band... Or the plain old fractional distillation, if we can live with associated loss of some fuel additives.
For home heating, spent transformer oil can be reportedly used as well. It burns hotter than regular oil, though, and is more difficult to ignite.
Selling counterfeit microprocessors with lower-than-advertised rating, low-quality knock-offs of aircraft parts made of sub-par materials, knockoff drugs that are contaminated or with different than listed amount of active component? That misleads the buyer and often does an actual harm. Bad, bad, bad.
Selling counterfeit clothes? Good. The only difference from non-brand clothes is way too often just the logo, and the demand for a thing with a logo is in this case driven merely by advertising. Such ad-generated feeling of a "need" is not genuine, and can therefore itself be considered counterfeit. Answering such counterfeit demand with a counterfeit supply is therefore perfectly ethical.
The GNU Radio folk can develop a passive radar system that pinpoints the UAVs at the moment they start broadcasting their video feed. Then the rocket enthusiasts can supply suitably scaled-down SAMs (sexy, dangerous, inefficient), or, with more sophisticated onboard electronics, even surface-to-air HARMs. Or, better, highly directional jammers that direct the drone into early death, or at least prevent it from receiving commands from the ground.
Why taking the platters out? Just tap the signals from the heads. Alternatively, replace the entire disk's electronics, and directly drive the heads actuator and read their output. Eventual bruteforcing then can take place in a large RAM on a portion of the disk.
Bigger rotor = higher linear velocity at the end of the blades for the same rpm. However bigger rotor also means bigger blades, which means more airflow at lower speed. So you can get bigger airflow with smaller blade velocity than with a smaller and much faster fan. You can be of course right; the combination of size/rpm is what determines the truth for any given fan.
I tried it successfully with a couple of my machines, as the original fans were dying and the replacement ones on hand were usually the power supply types.
A way to make a computer quieter is replacing the smaller fans with somewhat bigger ones, and slow down their rotation (eg. with a suitable series resistor). The aim is to get comparable airflow over the heatsink with lower fan blade speed, which means less turbulence over them, which means much less noise.
Will *you* work for what you call "sustainable wage", or is it a provision only for the "others"? How much is "sustainable"? What do you think you will you be able to buy for such money, what level of lifestyle?
Also, if everyone does the same, how many people will be able to do all the unrestrained consumption that keeps your economy afloat?
And what would happen would be a rehash of history. A quite small shit hitting a fan, couple days of stink and cleanup, some misdirected government overreaction, and then the life continues more or less like before. Happened many times in many contexts. Hardly worth sweating over. Hurricanes are worse.
Temporary loss of connectivity is nothing fatal, merely an inconvenience. Perhaps expensive inconvenience, but still a mere inconvenience. And while the attacks can be parallel, the repairs can be parallel too.
As a bonus, there would be less spam for couple days.
It's not like you can rethink the policies aimed at that issue later, after a dirty bomb full of cesium (or whatever's handy) has made 50 square city blocks in LA or Chicago unusuable for 20 years.
Boo hoo radiological dispersion devices boo hoo I fear. (Not.)
Movie-plot fearmongering. Specifically this is a non-issue; even if such device goes off, there will be little health damage, lots of shock (which is the goal), and some messup of local real estate market. Not enough for me to really worry. Do you know how many lives the hamburger stand on your corner can claim over the years? As long as the risk of being run over a car or getting a heart attack is significantly higher than the overly medialized but essentially unimportant terrorist-related mishaps, don't count with my support. Ever heard about moral panics?
If me or some of my loved ones die because of there weren't money for health care because it was wasted on "security", I will get mightily pissed.
Threat? What threat? 90% of weapons attempted to be smuggled to the airplanes get through. Count the number of real airplane incidents since S11 (five, including S11 itself, which was a statistical anomaly). Divide by number of the flights that you don't hear about because they are uneventful. To stay within the topic of airplanes, as a bonus assignment you may like to calculate the number of people who died after long-haul flights because of less newsworthy but still aircraft-related causes like eg. deep vein thrombosis.
Sir, people like *you*, the pushers of culture of fear together with its toxic fallout, are what I am truly afraid of.
Don't worry. By then there will be an alternative, officially unsanctioned player, based on something that will be perhaps called libdeaacs, perhaps with automated key updates via Freenet-like P2P, running on by-then obsolete hardware like a breeze and ported to just about every mainstream OS. Perhaps like a VLC Media Player with added decoding library.
Again, RS232 comes to rescue here. For some $50, there are eg. the Lantronix XPort adapters available, which are UART/TCP converters. They can either sit and listen for a connection (and then relay the bytes back and forth between UART pins and the socket), or actively open a connection to a defined IP:port. I have some supervisory hardware made this way. The UART/RS232 level converter can be made of two transistors, and all the other stuff you need is 3.3V/100(or so) mA for the module.

R12. (Old one.)
Do you care?
Yes.
Your question would make sense perhaps in some country with well-developed public transportation.
The GNU Radio folk can develop a passive radar system that pinpoints the UAVs at the moment they start broadcasting their video feed. Then the rocket enthusiasts can supply suitably scaled-down SAMs (sexy, dangerous, inefficient), or, with more sophisticated onboard electronics, even surface-to-air HARMs. Or, better, highly directional jammers that direct the drone into early death, or at least prevent it from receiving commands from the ground.
And there are various pesky side channels...

Just wait for autonomous robots.

Yawn.
You can buy one. If you buy from a neighbor for cash, you may even get it without tax.
You spelled "properly engineered" wrong.

A real linux junkie will just write a wrapper script. While pointclickistic interfaces have their place, they are way too overused.
