We live in a rural area with lots of narrow windy country roads with 60mph speed limit. My daughter has just passed her test and was coming home late at night - she was doing about 40 mph. A car sat on her bumper for about 2 miles making her really nervous, when she came to a village she pulled in to let him pass. He went past and then drove at 25 mph in front of her for a mile or so until she was able to turn off. The incident has shaken her up and given me another thing to worry about when she is driving.
