Due to an optical illusion, a train coming toward you is:
If your eyes tell you
the train is far enough away for you to safely cross, they may be lying. That’s
because large objects in motion seem to be moving more slowly than they really
are, and because our peripheral vision plays tricks on us, especially when
we’re moving forward and the large object is, too. The train may not seem close
until it’s virtually upon you, a phenomenon known as looming.
