I was reading the paper today about a skier
...losing control on an icy ski slope and colliding with a tree.
This seems to be rather a strange usage of collide; the word seems to me to carry the implication that the things that collide are both active agents, and the tree cannot by any stretch of the imagination be held responsible for this accident. This definition here seems to support that idea:-
to strike one another or one against the other with a forceful impact; come into violent contact; crash: The two cars collided with an ear-splitting crash.
Is that so, or can stationary or even immobile objects collide with things?
