Near misses and collissions happen every day - not just with automobiles/bikes but with atomobile to automobile. Of course, this is no surprise, but now you are more aware of it because a collision between an automobile and a bicycle is far more destructive to you as a bicyclist. Things can be damaged that money cannot repair.

You will become a more observant and safer bicylist as you learn not to assume anything about motor vehicle drivers or their machines.
