I have to say I'm always a little distressed by comments like, "The cops don't enforce the law because ..."
Cops also don't enforce drunk driving laws unless there is an acciddnet or some other egregious violation. Cops also don't enforce license suspensions and drunk drivers get their licenses taken away ever day in court then go out and drive away from the courthouse! People run red lights right in front of officers who let it pass simply because they are disinclined to deal with the paperwork or just don't want to get out and write a ticket.
There is never a good reason for an officer of the law to not ticket someone who is in violation of the law. Cops spend plenty of time cruising the streets ... what else are they doing out there while waiting for a call for some break-in somewhere or gunshots fired? Those "little" infractions they tend to overlook cause deaths. Unforgivable.
Newly licensed drivers tend to be young and inexperienced. They have not developed the "driving sense" that comes with years of on-road driving that gives them a heightened ability to gauge situations, timing, responses, etc. They are prone to joking with their friends in or outside their car, messing with the radio, talking on their cell phones. They tend to be more easily distracted by outside influences.
On a percentage basis of their age group, 16 - 18 y/o are involved in more accidents than any other group (including senior citizens) and yet most states require a minimal amount of driver training (if any) before allowing an adolescent on the road unsupervised. With rare exceptions, 60 hours of driver training is not enough to give a teenager the road experience they need to be safe drivers. My grandson was behind the wheel of a car at the age of 12. He was driving in empty parking lots, progressing to closed track. By the time he was old enough to get his permit, he was comfortable behind the wheel of a car and was not constantly thinking about everything he had to remember. Kind of like learning to write/spell or fly a plane, there is a learning process. It takes awhile to move from thinking through every step of the process to being able to do things reflexively. Driving I-465 in Indianapolis can be a daunting endeavor but my daughter joked she should ask for a refund from the driving school. It was "A++ Driving School" and he only got an A+ on his tests!
That being said, I wholeheartedly agree with the assessment to do the driving/chauffeuring yourself. And don't force your son to get behind the wheel of a car if he is not comfortable but, more than likely, he will one day want to get that license so you want him to get as much wheel time as possible. Keep his learner's permit up to date and encourage him to go driving with you whenever you can. If he is uncomfortable driving on busy streets, take him to rural areas where he will have less traffic to deal with. Make sure he is comfortable behind the wheel before he goes for his driver's license. And don't rely on church groups to be dependable judges of a driver's ability. A recent incident in Louisville, KY involved a group of kids leaving a church event one evening and, with many students getting dropped off but riding a church bus home, the bus was full before all students could get on. Chaperones allowed kids to ride home with students who drove. A tragic accident killed two brothers and their cousin on the way home that night after they were sent home with an older student.
Until you can control the situation and are absolutely, 100% sure your son is with a safe driver (preferably himself), you be his driver. It's a little inconvenient at times but, if something happened to him while riding in another kids car, you'd never forgive yourself. It's worth a little extra inconvenience to be sure he is as safe as he can be.
