A simple example of the use of devices, I placed player spawners throughout the track at various race checkpoint devices. Most of these start as disabled at the commencement of a round, but as the player passes checkpoints, the corresponding spawners are enabled, with the previous spawners being disabled, to ensure that if the player is killed, they will respawn at the appropriate checkpoint. On their spawners activating, it triggers a corresponding dirt bike spawner, spawning a bike and immediately assigning the player as driver. To disable the player getting off their bike, the bike is set to reassign the driver whenever the button is pressed to disembark the bike. This appears seamless in game, with the player not appearing to exit the vehicle at all.
