But most people have no idea about the senor(s) in tesla charger plugs, since it's a plug, not an alarm. How should it be obvious for the average layman without open disclaimers? People always tend to fuck with stuff they don't fully understand if someone tells them that doing something quirky means extra oomph. And forget about people putting towels on it, what about rain or wet debris falling on it? Seems like edge cases that should have been covered during the concept and design phase by EEs with experience. For something meant to survive and be used outdoor these are not even edge cases.
- dylan604 2y agoAre we confusing smoke detectors with fire alarms? Most people screw with the detectors. A fire alarm is usually triggered when a sprinkler head is set off. And despite what Hollywood shows us, just because one head starts does not mean all of the heads in the system open up.
- burnished 2y agoI think that one depends on the system. I had a highrise fire safety training and I asked how other sprinklers knew to fire if they were heat activated and it turns out the pumps would kick out enough pressure to knock the other caps off.
