I believe the trike pictured in the BBC "Foyle's War" program was used by a young rural woman to ride to town for groceries, and to carry her baby with her as she did her errands. It seemed to be a safe and stable,practical and inexpensive way to get around, particularly in times of "petrol" rationing. Racing something like this would be akin to "hot rodding" a machine that was never intended for racing....
