All I remember is: She was afraid of something, she wasn't pretty (to me) she had big strawberry blonde hair and because of her running into the street there was almost an multi car accident or could of caused an accident (don't remember)
Sorry it sounds very typical... The girl is afraid from a (killer?) she runs into the street nearly causing a car crash. I do suggest maybe check a few Giallo's between 1968 to 1975, although the movie you are looking for should be within 1971 to 1973.
sorry I wish I could help you on this...
