Roadblocks, such as the ones that show up in the default game when you're fleeing would be awesome. Either two patrol cars or the police van with cones blocking traffic, available through backup menu and would automatically setup a mile or so in front of suspect vehicle. I like how I've observed units parked on the side of the road join into pursuits. Maybe make EMS/Fire not aggressive towards police and not afraid of police gunfire Mechanic like in LCPDFR Also, for those who want a gang war type callout, simply drive into the area near Maze Bank Arena and call tons of SWAT and patrol units, then flip off or honk at the gang members on the sidewalk. An all out war between police and gang members will ensue.
