text: Opponents say that cell phones are good because they give an opportunity to make a call in case of emergency. However, it is an illusion of safety because when people need it the most either they can't find it or reach it because they are stuck in a car. "Texting while driving is the most dangerous activity on the road, even more dangerous than drinking and driving" ("Injured in a Car Accident by Someone Using a Cell Phone"). People shouldn't fully depend on cell phones because they are not reliable."You cannot drive safely unless the task of driving has your full attention. Any non-driving activity you engage in is a potential distraction and increases your risk of crashing"(Andrew Currin). Therefore, nowadays cell phones are unnecessary devices because they are unreliable in emergency situations .
