Not all redundancies are as bad as you argue. Sometimes even formidable English writers or speakers deliberately make pleonastic statements for the sake of adding emphasis and highliting their points. So don't always be automatically opposed to such constructions, but take time to see whether by making a repetition the writer or speaker has managed to argue the case more cleverly. I think you'll agree with me that ''I saw a speeding car hit a bicyclist with my own eyes'' is more emphatic than ''I saw a speeding car hit a bicyclist.''
