For obvious reasons, non-CBTC trains are not remotely controllable (CBTC essentially means "remotely driven"). It's all or nothing; either a safety system that inherently accepts the risk, or no way to remotely control the speed, short of fully stopping the train.
If modern cars have been fully remotely controllable for years, why can't police stop often-deadly car chases?
Ditto on air traffic control and small planes; many don't even have in-plane automatic pilots. AFAIK no ultralights ever do.
Most boats are not remotely controllable; even the large container ship that recently damaged a major US bridge didn't.
They want to retain the power of discretionary action. If the powers that be employed their 1984 stuff all the time over trivial things people wouldn't support them. Part of this means they don't give the beat cops those toys.
Also, there's a difference between "can be" and "are". Like there's god knows how many numbers of compatibility layers and intermediary systems I bet even if the capability exists it's broken more often than it's not. Diverse software systems take a ton of constant work to maintain.
During the "last years of XP" era you probably could have theoretically taken down half the world's industry on paper but if you tried to do so at scale without literal years of prep and testing you'd have been foiled by the 50% of machines where you payload just didn't work for some obscure reason.
Not putting this information in the fine print is fraudulent behaviour
Do you imagine some benevolent authority sits in your town with a finger on the kill switch for every vehicle in motion?
If it were in the specs from the beginning, there would be no issue. This isn't a "click here to accept" thing; multiple people scan the technical data in these projects.
Hm? Not a single bus on the road in my city can be turned off remotely. There's never been one ever, since bus transport started. So why should, no, must, that be a feature of new buses?
And when I said "Not a single bus on the road in my city can be turned off remotely", that's the truth. They can't. They're all diesel, so there's not even a remote possibility of a hidden esim-powered switch.
Why did the post I replied to claim that it must be possible for buses? And why did you assume that I meant something else, and that all buses are electric?
Edit: Typo
Every road vehicle sold today has a sim card, most for diagnostics, some for remote control.
Even you admit that most of them aren't for remote control, so what are you agreeing with?
