and for els just google els v6.1 or v6 i think the latest one is and download and itll tell you how to install if not theres many tutuorials on youtube and then after that just download els enabled models from here in the download section, make sure you download vehicle models and not textures that was my problem at first when i started playing. as for the shootouts and fleeing suspects i second the reply above pressing alt+f11 will give you random calloutsand if you do not get one you want, hit it again, and again and so on untill you see one you like! for your taxi bug or same type of vehicle bug, you will need to download traffic flow which is a script that loads up diffferent types of vehicles. also if you have online you could always start up a game by yourselfa and you will have different types of vehicles without traffic flow. as for bravehearts script the calls are very diferent and more over the place but you just have to remember the more scripts the more your game will lag/ or crash due to script failure. if you have any other questions or concerns to pm me or something!
