Will 'Talking' Cars Lead to Fewer Collisions? | CNBC

My opinion: this big data / data science technology - to track your vehicle movements to alert you of an imminent crash or to tell you that you drive too fast -  will create many false positives resulting in more collisions for a number of drivers (maybe for 10% of all drivers who outperform automated driving). But it can really help dumb drivers. So, depending on the driver, it could indeed work. Isn't this technology already implemented in planes? Or boats? Or even... pedestrians who bump into obstacles (sometimes killing themselves) because of cell phone and other distractions.

Another issue: Will car insurance companies use this device to track driver behavior to adjust your premium? Or will it be used by police departments to automatically issue speeding and other tickets? This could scare people away from this technology.

The article:

The U.S. Department of Transportation is launching the biggest study ever done on vehicle-to- vehicle communication in hopes of developing technology that could prevent thousands of crashes.

The goal is to see if cars communicating with each other can alert drivers early enough to help them avoid accidents.

"A year from now we will know a lot more about how we are going to save injuries and save lives," said Secretary of Transportation Ray LaHood.

The study will involve 2,800 vehicles in Ann Arbor, Michigan equipped with sensors and technology allowing them to constantly send out and receive signals showing their position, speed and other data. 365 vehicles in the study will have technology to warn drivers when they about drive into another car. For example, the driver’s seat may vibrate on the right side if the driver is about to change lanes into another car.
