There are several reasons engineers are developing driverless cars. First, these cars will make driving safer. Most car accidents are caused by human mistakes: falling asleep behind the wheel, drinking too much alcohol, writing a text message, etc. If the car's computer was in charge of driving, human mistakes would not be as dangerous.
Another reason is to save time. A driverless car could drop you off at work and then find a parking spot on its own--no more searching for a parking spot. Also, while your car is driving you around, you can read a book, prepare for work, or make a phone call. This would save you time later during the day
Experts believe everyone will use driverless cars in the future. Cars are already made with computer sensors and video cameras. Newer cars beep if they get too close to another object. Large vehicles use cameras to see behind them before backing out. lt's just a matter of time before we see driverless cars on the freeway. 94.
