Is there a defined standard for car-to-car communications or will each car only talk to others of the same make/model/version/software revision...?
General Motors to intro hands-free driving tech by 2016
General Motors is planning to release cars that can communicate with each other to avoid traffic congestion and accidental collisions as early as 2016, its chief exec said. Mary Barra announced over the weekend that the car giant was planning talkative automobiles and more advanced tech to allow hands-free driving as well. "A …

Worried? Me?
I mean, it's not as if GM would use defective parts (and deny the fact for a decade) for their self-driving cars, is it? So, nothing to worry about then.

Re: Worried? Me?
GM has made garbage since the 80's. They deny any defects until they can no longer be denied. The "new" GM is no different from the "old" GM. You have the same culture and the same group brought up in the old culture running the new. You can't expect change when nothing has really changed.

Hands free driving seems like a really bad idea
No way is a driver who doesn't even have their hands on the wheel going to react quickly enough in an emergency situation when the car hands control back over to the driver.
Especially if the driver is eating a messy burger or messing with their laptop or phone. It'll take their brain a second or two to change focus from what they were doing to take in what is around them and determine what to do. That second or two is going to lead to accidents that wouldn't have happened if the driver was forced to remain in control and aware of his surroundings the whole time.
This is worse than a driver who is texting, because at least someone texting is switching his attention between driving and texting, and maintains a good deal of awareness of what is going on around him. A hands free driver might not have looked at the road for a half hour when he's called upon to suddenly take over driving the car!

Re: Hands free driving seems like a really bad idea
I am minded to believe that the car will fail as safely as possible. It is unlikely that all systems (speed sensors, approach sensors, V2V comms etc all fail at the same time but if they do there is no reason to believe that it would happen right at the moment of emergency and it could fail cutting power until the accelerator/brake are pressed. Separate circuits/CPUs can control different aspects of the automation so there isn't a catastrophic failure and all the systems can be continuously sense checked so that alerts are given in plenty of time.
You trust your lives to the computers in a plane every time you fly. If the main electrics and computers in a modern car packed up while on a busy motorway at high speed you'd probably have major issues as it drops into limp mode. However it is extremely rare and we don't worry about it.
Sure, there could be major failures and it could cause accidents and even death, but then again the amount of accidents caused by a person being left to control a car is so high, they would have to do a pretty poor job to reach that level of incompetence.
The bigger problem is going to be, if they are so reliable that after many years automated driving you start to forget how to drive manually in an emergency.

@AC
I'm not talking about any systems failing. I'm talking about systems that will be designed for specific scenarios, and will hand control back over to the driver outside those scenarios. Let's say a car ahead of you starts skidding back and forth out of control. The computer is designed for lane keeping and such isn't going to try to dodge that for you, it is going to hand control to you to do (or not) the dodging yourself.
If you've got your hands on the wheel and are paying attention, you have a much better chance of dodging that car than if you've been reading Facebook updates and suddenly the car alerts you that you need to take control and you look up and take in the scene and probably run right into that out of control car before your brain has time to evaluate the situation and determine the best way to avoid a collision.

A computer will be able to do a much better job in this scenario than most, if not all human drivers. If you've actually been behind a car when it starts fishtailing there is no way to 'dodge' it until it starts coming to a halt. You just brake as hard as possible without skidding yourself.
A computer could calculate the optimal braking under any given condition better than a human can and at the end of the day if a collision is inevitable then going at the slowest you possibly can when it happens (apart from something like a juggernaut rear-ending you) the better - even more so if the computer has already activated your flashers and sent a communication to all cars approaching (and the electronic traffic signs, police etc) that there is an incident ahead.

Super Cruise
This is (or could be) pretty cool, but doesn't the name sound something like one of the hyperbole-laced feature names of the 60s? Sounds kind of like Positraction (independent rear suspension) or Hydromatic (automatic) transmissions.
"Super Cruise" sounds a little like one of those.

Meanwhile in other news...
hordes of lawyers were reported as salivating at the lips with the thoughts of the huge lawsuits that they'd soon be filing against GM (and any other car maker who introduces this in the near future)
Also real estate brokers in the Carribean were reporting a large number of inquiries for properties in the $50M+ price band.

What about my 1990s Honda?
Does this mean GM won't know I am driving towards them in my low-tech 1990s Honda?
Or will this open up a market for a Google App which will mimic these systems letting me drive down the road shouting "Get out of my way" in the various car languages.
Now if this App could just be combined with an App to turn all the traffic lights to green as I approach... I think I may have just designed the next "must have" driving app.
