(the land speed record (or absolute land speed record) is the highest speed achieved by a person using a ‘vehicle’ on ‘land’)
(there is no ‘single body’ for ‘validation’ and ‘regulation’; in practice the ‘category C’ (“Special Vehicles”) flying start regulations are used, officiated by regional or national organizations under the auspices of the “Fédération Internationale de l’Automobile”)
(the land speed record (LSR) is standardized as the speed over a course of fixed length, averaged over two runs (commonly called “passes”))
(2 runs are required in opposite directions within one hour, and a new record mark must exceed the previous one by at least 1% to be validated)
