text: Many advocates for the way things used to be will say that any use of the phone should be prohibited, that any use at all can cause a wreck. I completely agree, if used incorrectly, cell phones can be detrimental to whoever is on the road with you, but one thing some of these advocates don't think about is the amount of people who are safer due to their phone. Some insurance companies have apps which track and adjust rates based on the person's driving. If it weren't for GPS, many people would miss exits, swerve to get in their lane, and in general make dumb mistakes which could lead to more harm than good.
