I think it really depends on the kid, if they obey rules and do not lie and are trust worthy. For girls, by the time they are eighteen many are in Israel for the year in seminary. They come home from that year and have to drive for work or to go to school. Many will have to commute long distances. For this reason I think it is good for a girl to learn how to drive and get lots of experience before she leaves for Israel if she will need to drive when she comes home.
I am also a big believer in kids taking the driver’s ed class. Teaches them many good pointers and you get off on your insurance. Also keep your Tehillim handy to daven that they drive to and fro safe and sound!
