There is no defense for texting or cell phone usage (other than calls to 911) while driving. Our of our state senators has a "mobile office" in a van driven by one of his staff members. After following him and his erratic moves during a morning drive downtown, I called the senator's local office and complained. The person answering the phone said she would report this to the staffer's supervisor. The senator is in a tight race next year--'nuff said.
