According to the US Department of Transportation, there were circa 6 million
police reported crashes in 2017.
In some accidents, the driver could be distracted for a few seconds (checking the
phone, texting) or it could be over speeding vehicles skipping the traffic light,
accidents due to driving under the influence of alcohol or drugs, and sometimes
due to non-conducive road conditions, e.g., icy slippery roads or obstacles on the
road.
There is a lot of interest in the automotive industry to upgrade cars and heavy
vehicles with more advanced safety features.
Until now, discreet physical features in the car, such as multiple airbags and
strong body/chassis, were touted as features providing the most safety to
passengers.
The latest trend is to use ubiquitous connectivity around us to provide much
advanced warnings to the driver or the car of an impending accident.

The current generation cars have the BSW (Blind Spot Warning) camera as a
common feature.
Some cars are even offering front and side facing cameras.
Radars and more expensive, but high performing lidar are also being incorporated
to assess the surroundings of the car.
These sensors are unable to provide 360 degree vision of the surrounding of the
car when there could be impediments, e.g., blind bend corner or buildings or large
vehicles blocking the field of view.
In such situations, V2X sensor complements these other sensors and provides the
see through, 360 degree non line-of-sight vision (well beyond the drivers’ horizon).
