Have you been pulled over and cited for using your phone’s map/GPS? Or have you been arrested for DUI or drugs, with the officer(s) stating that they had probable cause to pull you over because you were on your phone?
California recently ruled that it is okay to read your cellphone map.GPS while driving. http://www.nbclosangeles.com/news/national-international/Drivers-Can-Read-Cellphone-Maps-California-Court-247644341.html
Not saying that you use your phone while driving, as that would be against the law BUT it is completely fine to drive and use your cellphone’s GPS.
