some time ago, traveling down the A130 from Chelmsford in a line of cars, when 2 suitcases decided to go air borne off the roof rack from the car in front obviously not lshed down by the driver.
avoiding action taken, i chased the errant car and pulled along side to be given 'the finger' by 2 'ladies'.
so suitably charmed, i finally got them to pull over before they lost the remaining suitcase, where i explained fairly graphically why i had chased them, but not a word of apology and did not even look at me
