15: Blind-Spot Monitors
Blind-spot monitors have become the norm in most modern vehicles, but there was a time when this technology was in its infancy. The earliest blind spot monitoring systems were simplistic devices that would beep when the vehicle was too close to something. This was an easy way for the driver to park without all of the fuss that comes with looking out your blind spot.

The current blind-spot monitoring systems have managed to change the way that we drive. These new technologies have continued to make driving a much safer experience, and the blind spot is one of the most crucial parts of driving a car.
