I think this is absolutely brilliant and too long in coming. I agree that the addition of it as an option will likely drive consumers to want it (think Consumer Reports, "The Safest Cars."). It will also be great for new drivers who are still working out the nuances of driving.

Impaired drivers

As the article says, car-to-car will not assist with impaired drivers. One of the biggest causes of accidents where I live seems to still be impaired drivers. I wish there was some way to prevent a car from starting if a driver is under the influence or too tired. True, the passenger could "take the test" but I think it might hit many people with the truth that they are really *not* "OK to drive."

I am not sure I would call it brilliant...it sounds to me like pushing the technology down the throats of consumers...I personally have no interests in using it, or even more importantly paying for it...and if most people are like me the value of car to car communication will be pretty slow...and what if they speak different languages!

Now if people want to rob me and/or steal my car, all they have to do is spoof broken down cars ahead of me so my car stops itself, or trigger the kill switch.

The problem with cars is not that they are too simple and need myriad more failure modes.  Can you imagine the chaos with all cars out there running different versions of the V2V software, and the chaos when 50% of them don't start some morning because they received an automatic update overnight that bricked their computers?

All they need to do is enforce impaired driving laws more rigorously, and take licences away from people who have demonstrated that they aren't responsible enough to be trusted with one.  This would have the side-benefit of increasing demand for public transportation, which in turn improves its quality, so people don't need to drive as much.  Plus, you get the health benefits of having a population which walks more (to get to and from public transit), saving national health care costs.  This is IMO a big reason why Europeans are healthier than Americans.

Here's one approach (now deployed in ~25,000 aircraft):

Ha, ha, Kris,  "Speaking different languages!"I wouldn't go that far and be so pessimistic.

The technology has been tested for many years in Michigan. It's known to work. The issue is that this has been such a long process that some of us are worried that the window of opportunity to really leverage DSRC might be closing...

The testbed in Michigan does not include the use of other wireless technologies such as a driver's smartphones. Considering the progress of technologies these days, DSRC, if watied too long, could become a thing of the past.

Junko, I live in Canada and drive to US fairly frequently...I would imagine that Mexico-US border is even more busy...so different "language" (or more likely car to car communication standards) is a remote possibility...after all you guys stick to miles and we use km, hundreds of years has passed and this simple issue has not been resolved! And now you want my car to talk to your car!! Imagine confusion if my calculates everything in meters and yours in inches...Kris

@kris, well put and well argued. I had not thought of that before!
