For the London to Brighton run my great uncle Roger used to drive down to London from near King's Lynn in his 1903 de Dion Bouton. He always considered the run itself to be a trifle & was always rather dismissive of the cars that arrived on trailers. One time, when driving from London back up to Norfolk in it he was stopped by a police roadblock. When he asked one of the plods what they were looking for, the reply was a cheery "Don't you worry about that sir - we're looking for a murderer, not a lunatic".
