Comment: Overloading unprepared equipment isn't difficult. (Score 1) 94

" Those who created and programmed Stuxnet needed to know the exact amount of pressure or torque needed to damage aluminum rotors within them, sabotaging the country's uranium enrichment operation."

Mechanic with machinist training here. That's no big deal. Overloading a system by running it as hard as the drive motors allow will often break it as many machines aren't built with protective mechanical safeties such as simple wasp-waist shear points on driveshafts, shear pins, or mechanical governors.

It's easier to control machinery electrically and when a targeted operator doesn't expect malicious control operation they aren't likely to have designed with it in mind.

"what about if a car came along that didn't have wheels?"

They have. It's called a "hovercraft" and proponents saw them as the wave of the future.
They are inefficient, lack positive steering or braking (good luck stopping one on a downgrade) and remain in the niche markets they suit.

If a future wheel-free car is offered, I won't need to "try" it to determine if it suits my requirements. I can infer that from what I see it do.
