text: Using a GPS system on your phone while driving helps us to get to our destination easier and lets us focus on the road better. If we did not have a GPS and we were to look for signs to go anywhere, we would be very much likely to get distracted or get tired quickly. Yes, it is true that we can replace our phone's GPS with a GPS device, but again, if the driver is not misusing cellphones, it is essentially getting the same job done. Also, because smartphones are easier to control and easier to interact quick than a GPS device, it will reduce the frustration of the driver.
