Request the vehicle recording defined by the lowercase format string "%s%03d.yvr". For example, REQUEST_VEHICLE_RECORDING(1, "FBIs1UBER") corresponds to fbis1uber001.yvr.
For all vehicle recording/playback natives, "script" is a common prefix that usually corresponds to the script/mission the recording is used in, "recording" is its int suffix, and "id" (e.g., in native GET_TOTAL_DURATION_OF_VEHICLE_RECORDING_ID) corresponds to a unique identifier within the recording streaming module.
Note that only 24 recordings (hardcoded in multiple places) can ever active at a given time before clobbering begins.
