In the past, most rally courses were not allowed to be scanned prior to the race, and the co-drivers used only maps supplied by the organization. The exact route of the rally often remained secret until race day. Modern rallies have mostly converted to using organizer-supplied notes or allowing full reconnaissance, as opposed to racing the stages blindly. This change has been brought on in large part due to competitor demand. Because pacenotes allow a driver to plan for upcoming turns and road conditions, recce makes the competition experience faster, safer, and more satisfying for the entrant.
