Reply to comment by dimonium_anonimo in Eli5 why do traffic lights have red, yellow and green color? Why not use other colors so that even colourblind people can drive. by [deleted]

Wait, this sounds like it’s still consistent with stoplights. Green means safe/off and you can interact with said machine (equally for cars, you can interact and drive through) whereas red means danger/energized (for cars, you should not interact with driving and stop the car). For me, this sounds like it checks out! 👍

The counterintuitive part is that you normally think about things from the perspective of your car. Your car goes on green and stops on red. My machine goes when I flip the switch to red and stops when I flip the switch to green. If you think about someone else's car at the stoplight, then fine, this matches well, but I also think you're weird if you do that.
