Imagine living in a universe where, without even trying, you can run so fast that if you trip, you will die and splatter your body over a couple hundred meters of ground. And if you trip into someone, it’ll kill them and possibly an entire pile of people.
Like, in motor racing, the cars get wrecked but the drivers are fine. In the movie Cars, they all die. The race spectators are watching a blood sport.
But trying to extrapolate from nonsense movies is the fun part!
Let me rephrase, I’m not trying to make the world of cars more realistic, I’m trying to imagine “what if we were as relatively fragile as cars are”. What if our normal every day activities like walking were as risky to us as driving is to a car.
