text: All in all, limiting the use of cars has more advantages than disadvantages. Most of the potential problems could be easily fixed with a little bit of brain power. Opening more jobs and cleaning up the envirenment should be reason enough to switch over to a car-free lifestyle.    I think that the first policy, that students should be allowed to bring cell phones to school and use them during free periods or lunch as long as they are turned off during class is the better policy. You should let the students use them first because that will reduce the amount of times kids try to sneak their phones, and get in trouble, including during class. If you let them use during lunch and free periods, then the kids will be happy to have gotten to use it at all, and therefore have no reason to sneak it in class.
