I'm sure you know the train question. If a train is going along and the conductor sees a child on the rails, but can change rails to another track, but that one has five. What do you do?
The actual answer is changing tracks has the train going slow so it doesn't derail. I have had family in the train engineering business for generations. So the actual answer is, the brakes you're going slow enough to stop easily.
I realized that yesterday while watching some old Doctor Who near a train station.
Anyway, the reason why I bring it up is I am arguing with someone that the answer is there, but not given by the original question. Also, no one thought to ask anyone in the train industry. I looked the guy up, and he's a lefty. It makes me realize that much of our society is based on the idea of false choices. There is always another answer, but the media and government act as if there is no alternatives. Then we make sure to ignore all evidence pointing to alternatives. This is society, trying to make a choice while the train stops on its own.
I haven't heard that since uni. Yes, it is the dialect. Good point. The guy I was arguing with also said it was for drones and cars. I pointed out it's already been solved. A drone has to get permission to fire, it's not automatic. The car hits the brakes, and the driver is warned way before. You'll notice the other commenters still don't believe it.
