It’s also how baseball players catch balls, how many animals catch their prey, etc.

There’s no need to estimate position and speed of objects and then extrapolate them to predict whether course collide and how long that will take. It’s easier to directly derive that from optical information (think of it this way: if that train is 10% as far away, and also goes 10% faster, it will still hit you at the same time. That’s a degree of freedom brains don’t have to solve for)
