Like with any technology it always sounds great at first. Given the propensity of today's drivers to be distracted already with much more important tasks such as phone conversing, reading, texting, etc in the car, would MORE information make them pay attention? Maybe if the system sent them a text message..."WARNING, Idiot driver in cross traffic at the upcoming intersetion is about to run a red light!" Then the driver may pay attention!
I sure hope designers are paying attention to security! I can see it now, in the short term when the car only gives the driver warnings: Kids on the side of the road with a rogue transmitter telling passing cars the non-existent light ahead will be turning red... or later when the car makes decisions for you, the same scenario making the car stop!!
Then there are the criminal intents, the privacy issues (each car would be uniquely identifiable i'm sure), plus unintentional interference (or intentional jamming).
The way automotive electronics systems have been designed thus far isn't very comforting.
I'm not saying it should be abandoned, just that we need to make sure it is implemented correctly!
We'll have to install these transmitters on deer and other critters too, so when they cross roads, cars are aware! :)
Definitely a technology to keep on the radar screen. While I do think V2V Communications has life saving potential, as with any of these emerging technologies, there are questions about it, more in the short term, before it's fully evolved. One thing that occurs to me is say all these new vehicles are equipped with the sensing, receivers, and GPS technology to make this work, what about the older vehicles that don't have the requisite technology on board? All it takes is one of these to blow a stop sign and any driver in the cross path depending on his or her onboard warning system is toast.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
Using almost 200 light-emitting diodes in the front and back of the new 2014 CTS, Cadillac designers are showing how LEDs can change the character of a vehicle.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
