I did check if this has been already requested and I couldn't see anything.
I was just like to suggest being able to use SWAT SUV's as patrol cars. Similar to the k9 unit. I would assume that SWAT SUV's would be able to respond to lower priority emergency's. Some examples of this could be a stabbing or brawl. If I am correct in the US a SWAT SUV would be able to respond to this call however the game does not cater for this.
Thank you,
