So, if I understand this, correctly, any vehicle equipped with blue tooth technology would disable the smartphone closest to the drivers seat. Wonder how they are going to deal with that in police cars. Within the past week I have seen 2 near accidents involving cruisers where the officer was on a cell phone, one where the cruiser just continued on through a red light. How would this technology deal with a case where the engine, for whatever reason, is running and the phone user needed to call 911?
