My dad worked for AAA. Once he got a call because a lady’s car errored out and thought she didn’t have her seatbelt buckled mid-drive, so it shut the engine off. On the freeway.
Even without a subscription, failsafes should always fail safe.
Thorium reactors have a cleverly dumb failsafe. If reactor control fails, there’s a plug that melts and drains the contents into a container that’s not fit for runoff neutron generation.
That’s an example of a failsafe that fits its purpose. It’s still possible to fuck it up, but it would take a lot of effort to do so.
