I believe some is going to have to get them interested in driving and cars first, and then work them up to an interest in airhorns on big trucks. A friends has twins (a boy and a girl) that are both 18, recent HS graduates, and now in college. They both obtained learner permits but allowed them to lapse due to lack of interest and experience. WTH? Phones, computers,video games, and TV are more interesting than the escape and adventure provided by being able to drive?
