I was thinking of a mod someone should create. You know you see cops on traffic stops in the real world, I feel as though there should be a possibility to where you can spawn other cop cars around the GTA V world that are on traffic stops and you are able to stop behind them and assist them. Otherwise another thing could be a callout to where an officer would like back up on a traffic stop. If anyone knows if this is possible or if the inclusion will be made in the future LSPDFR update please reply and let me know.
