New Car Technology Tells Tailgaters To Back Off

In 2009, more than 30,000 Americans were killed in car crashes. Most of those accidents were avoidable — the result of driver error.
Now, the auto industry wants to cut down on traffic deaths by using vehicle-to-vehicle communications technology.
The technology enables cars in close proximity to one another to share information wirelessly. The premise behind it is that most crashes are avoidable if drivers have enough time to react.
