Alfred Charles William Harmsworth, Motors and Motor-Driving (1902)
“ As every person interested in motor carriages knows, until the passing of the Locomotives on Highways Act of 1896, every mechanically driven carriage had to be preceded by a man on foot with a red flag, and proceed at a pace resembling that of an ox waggon. But now we may, if our vehicle be under a ton and a half, move at the pace of an average horse, that is to say at twelve miles an hour. ”
