The mod for Emergency 3 is not more realistic. You are also wrong on a few points. The FBI is a federal agency and does not perform patrol tasks like the police does. In real life, cars do almost never explode. In EM3 and EM4 it's almost like every car is rigged with an explosive device. The longer it takes before a vehicle explodes the better. You are right about the MP5 though, but you can change that easily yourself in the scripts. For gameplay's sake, it does not kill/injure a person immediatly. Your preference for the lights in EM3 is only a personal taste. I consider the lights in the LA Mod for EM4 more realistic, because they were reviewed and changed by Mikesphotos who actually lives in LA and works there at the fire department. You got permission to release the grey FBI car as submod to the Los Angeles Mod.
