I definitely think that to keep with the realism theme, car theft should definitely be an option for the criminal aspect. As you CAN steal cars in real life, but its not the skill set of any old John Q. Public. I know theres alot of police officers that jave offered their knowledge up for the developers to pick their brains, So i can offer my aspect from the criminal perspective. Theres a few different ways you can break into a car, but to what end. Will there be a criminal enterprise that can actually chop up a car, and distribute parts, or change out VIN numbers and clean papers? Or will u just be able to steal a car to joyride, or if ur trying to escape the police? You can steal a car the brute force way, smash the window, hotwire the car, and go. If there is an alarm system, that must be disabled before hand. This is assuming there will just be keys to start ur car. I can't imagine they will go as far as chipped keys, that you physically cant start the car without. Or will they? If the car is expensive enough? Then you got the professional way, jimmy the door, bypass or disable alarm, start car, take off. If its an expensive car it should have a more sofisticated system to bypass. Or it will be, if its expensive u just cant steal it. Probably be simpler to only be able to steal middle to low end cars, as it can become a pretty complicated system if u try to make it too real...Wow what a mouthful
