Making a car difficult to steal

I would sleep pretty well in a rough area with just a kill switch. The whole idea behind people using tow trucks to take cars is exaggerated big time. Most car thefts are a result of keys left in cars or on the rare occasion a hot wire. I'm not saying that card aren't stolen with two trucks. I just don't believe it happens enough to be a big issue. Maybe an alarm system to catch all the coat hanger guys.
