Margaret Thatcher witnessed and rode on the steam train, the bullet train, enjoyed fuel injected non-leaded fuel for the routemaster buses and she rode on the hydrogen fueled doubdeckers and in a hydrogen fueled Aston Martin. Her present age was a zero emission age as a proponent of common sense( 2 for 1 at Tescos) and change.  Her economics were "Stock the kitchen cupboard" economics.  As ING said, she aimed to "...save your money." She is remembered rather intelligently.
