On relativity

It is said that the great theory of relativity of Einstein's doesn't apply to things moving slowly. Today I realized that is not true. There is a direct relationship between space and time and speed affects space, so it must affect time. Here is a practical example: a car moves faster than a person walking, so its speed makes distance shrink relative to time. Inversely, that means that it makes time expand, become more expensive, from the car's point of view.

That is why, when you see a car approaching and you have the option of walking in front of it forcing it to stop, you wait, because the driver's time is more expensive than yours. Stopping the car and wasting time would impact him much more than it would you. It also has the side effect that it saves your life if the car doesn't stop for some reason.

Just a thought.
