We visit the Drome area of France about three times a year, sometimes on the bike and sometimes flying and picking up a rental car. I agree with Thornley in that the driving standards are abysmal, especially on what we would call A and B roads. The average Frenchman or Lady sees the vehicle in front as an obstacle to his progress, a challenge to his superior driving skills, and as such must be passed at all costs. I don't dawdle and yet many times we have been overtaken by French drivers on blind bends just to gain few minutes before arriving at their destination. The number of cars we have seen in ditches after a sudden summer rain shower is unbelievable.
The French can be the most helpful, polite and courteous people yet put them behind the wheel and they become absolute morons which is a shame.
