"One peculiarity of human perception is that large objects in motion appear to be moving more slowly than they really are" - Folks, never cross the roads/tracks when you see a vehicle approaching. Wait for it to pass and then cross.
- Jabbles 6y agoCrossing roads is different - and it would be often impossible if you had to wait until no vehicle was approaching. But as this article points out, you can't use your experience judging car distance/speed to judge train distance/speed.

- emmelaich 6y agoHow far away is the vehicle? How much time do you have? From a fairly recent HN article -- see Lamport's discussion of Buridan's principle. http://lamport.azurewebsites.net/pubs/pubs.html#buridan http://lamport.azurewebsites.net/pubs/pubs.html#buridan
