I know that Nuke, but the Illegals are not animals that you can park. Those are people like you and me that have a life, and part of it is do get from A to B, for the same reasons as us (work/familly/grocery shopping).
If they had the balls to leave everything they knew to come in USA, it's not "u should not drive" that is going to stop them. Most illegal I know, work their but off in construction jobs, make money, have a life like you. Except they are illegals, so they can't get back in status with INS except by some magic costly loopyloop. So, they don't pay taxes, don't get car issurance, and live a normal life with a damocles sword above their heads.
try to remove them of the road, and next thing they will do is to steal a car every morning to get to where they need to go. I believe it's foolish to try to manage them once they in USA. Heck, give them a driving licence, an inssurance, and let INS pick them up the next week thank to the Fed/state x-soed database.
The thing is, INS doesn't give a penny about Luis Lopez. As an example, when I was illegal they always knew where I lived. They never came to "pick me up". And I was flying airplanes with radioactive stuff in it:rolleyes:, legally declared to the FAA. You would think it would have raised a concern.
