It seems you are really concerned with safe driving. Thats good. Perhaps instead of peering into other vehicles, you could watch the road. After all, all it takes is a split second of distraction and SPLAT goes their car.
Are you also concerned with people eating while driving, disciplining children, reading maps, looking for CD's, cassettes, talking to the person in the seat next to them, reading books, newspapers, etc?
