Women and Range-Rovers........

Actually nothing to do with Gillian Taylforth's lay-by antics so well documented a while ago,but more a need to discover the driving logic applied by the more well-heeled laydees to their 4x4's.Not your Suzuki Vitara or Honda HRV runabouts,but the two-and-a-half ton,fifty-grand,petrol guzzling monsters we see ferrying little Tarquin and his sister Clarissa to prep school every morning.Forgive me if I am wrong,but I am sure the design chaps at Range Rover(or Nissan,Toyota,even Mercedes)were very thorough when planning out the suspension systems on their respective 4x4's.Designed to tackle the roughest terrain in some of the most inhospitable places on Earth,years of research and testing have gone into the production of these go-anywhere vehicles.......

........so answer me this:WHY DO WOMEN DRIVERS IN EXPENSIVE OFF-ROADERS SLOW DOWN TO 5mph FOR SPEED-BUMPS???????
