I was playing last night and I got in pursuit of a suspect who was flying over route 1 and eventually on the Pacific coastal highway. Due to heavier traffic, I fell back a bit and was responding behind two other units. It gave a sense of realism where I wasn't always the first one to a call, where I am always reacting to what was going on and having to call backup myself. It was one of my favorite moments in a while.
After talking to others, a common issue we have is a sense of being alone on shift. I feel like I have a solution that can mitigate it, and should be fairly simple to implement.
Back in LCPDFR, there was a kind of hidden feature where if you set a waypoint, you could call for backup and a unit would spawn next to you then respond to the waypoint alongside you. Such a feature could easily be implemented, and with features that didn't exist before like code 2 backup, it will give a sense of an actual department responding instead of a lone player who shows up first and reacts to everything. A nice feature would also be the ability to have backup stick around until dismissed, like in OnScene backup.
