Y'all should make it where you can control a message board on/off, change messages on the board. And have controls like only light wig-wags or front of a light bar only or back of light bar only. Basically I think it would be awesome if you made it where you can have a message board and control it on and off. And make it scroll instead of flash. I would also love it if there was like something to control beacons in cars such as an amber beacon.
It would also be cool if you could change the speed of the beacon.
You should add fire department options.
Also you should make it where cops are at the road block if so how many. And if there cop cars are behind the road block, and if lethal force is authorized or in authorized, and spike strips.
Just a little side 1 you can choose a certain type of fire department vehicle respons (i.e. pumper, ladder)
