Emergency Situations

• If you find yourself in a situation with a broken down car, a cell phone can save the day. Instead of walking miles to find help, you can simply call for it from your cell phone. This is convenient, quick and could save lives in an emergency.
  
  Your cell phone can also benefit others in need of help. If you're in a no-phone zone and you witness a car accident, you cannot call for help immediately and would have to waste precious minutes to drive to a landline to get assistance for the victims.
  
  

Navigation

• Many cell phones are equipped with a GPS system that can help you to find your way to places that you have never been. These GPS systems give far more detailed directions than you would find using a regular map. They also allow you to re-route your trip in a matter of seconds if plans change. If your car is a dedicated no-phone zone, you lose the convenience of GPS and may have a more difficult time finding your way to new destinations.
  
  

Convenient Contact

• Cell phones allow you to stay in contact with friends and family. If someone needs to get in contact with you, he can do so instantly by calling your cell phone. If you are in a no-phone zone, people will not be able to contact you, which can be inconvenient. Cell phones also come in handy if you are running late, forget something, or get lost. When you enter a no-phone zone, you lose the convenience of being able to make a call to alert someone about your situation.
  
  

Entertainment

• Cell phones can serve as a form of entertainment, as long as the person is not driving or participating in an activity that requires his attention. For example, instead of fighting over which radio station to listen to in the car, passengers can entertain themselves by browsing the Internet and playing games on their cell phones. If your car is a designated no-phone zone, you may have to deal with cranky, bored passengers that are lacking the entertainment of their cell phones.
