It just occured to me, in his opening post, Wee Tam tried to make us doubt the existence of the 'car that didn't stop'.
Maybe it was the same car that, a few years earlier, according to some witnesses, helped rob us of the existence of Senior Aircraftsman T.E. Shaw, near his home close to Bovington Camp Dorset. This car also didn't stop, was never traced, and doubt was also cast on its very existence.
