This document indicates the development of Formula One racing and the corresponding increase in the number of race incidents, over the period 1963-99, in which unprecedented advances in the application of technology and aerodynamics to the cars produced remarkable potential for increasing performance. It shows for each period considered the continuous action taken by the FIA and the Formula One Teams in developing and applying measures to progressively contain the consequences of accidents, latterly achieving levels of risk which are minimal for participants and negligible for spectators.
