Interesting and exciting, but let them test it in Korea first. 😛 

That's scary knowing how scatter brained or slow some people think while driving out there. No thanks.

This is actually to address that.... it will filter out the unsafe driving bits and smooth out the good driving bits.  It should make those bad drivers more predictable.

Yeah, I see what they are trying to do, but being able to filter all of that out will be a large task. "Traffic is stopping I should probably start applying the brakes...look a squirrel!!" 🤣

I think what GM has been working on for a few years might work better with what they call V2V (Vehicle to Vehicle) where vehicles will communicate with others knowing what's going on ahead and behind and can react earlier and faster than the largely distracted human being behind the wheel. It would start with GM vehicles and would probably become an industry standard. GM says this would help with the "rubber band effect" in rush hour making it much more consistent while keeping vehicles moving smoothly when merging as well as being evenly spaced from each vehicle.

GM already had V2V in the CTS.  I don't know how well it worked or if they even put it in the CT5.

I don't think it was the full V2V with the CTS though, could be wrong. What year of CTS? I know the CT4 and CT5 as well as the C8 Vette have the new GM "digital nervous system" wiring schematic that ties all the vehicles functions into several different sensors, so they may have a next gen. V2V that works in conjunction with that.  

They had a system in place with a CT6 Platinum that I had for a 24hr. test drive that works in conjunction with Super Cruise and they've been continuing to test it and seems like they were on the right track, but who knows with all the GM Corp. general counsel involved.  

Well the problem was that it could only talk to other CTSes because they were the only model with it, so unless you were about to rear end another CTS in your CTS, the system didn't do a whole lot.

Well, not exactly because the car ahead of you can be several cars up so it doesn't have to be directly in front of you to communicate with the other to know that traffic is slowing or stopping up ahead. If all GM vehicles eventually had V2V that would be key to a successful implementation of it.

Every car would need it for it to be successful

As far as I've read and heard it's not meant to always drive the car autonomously, but has adaptive brake control/accident avoidance included to slow and/or stop the car. Just like all cars now don't have active braking or other safety features, but if even just a few in the local traffic have V2V then they can at least be alerted of slowing or stopped traffic several cars or even just 3 or 4 vehicles ahead and not just the one in front of you. There's really no perfect scenario, just like this Hyundai system.

I'd rather be involved and drive the vehicle myself anyway   

V2V sounds useless unless everybody got together to work on a system for every manufacturer. Even if all GM vehicles had it, it would still be useless as there aren't enough on the roads. 

(That's not some weird sales dig. There are just too many other manufacturers and nobody has even 50% total market share)

GM has not had 50% market share (in the USA) since 1980.  You are correct in that V2V needs some real technical interoperability standards for it to work consistently.

Oh I just threw out a number of vehicles that still wouldn't make it super successful and unrealistic to obtain(50% market share across the board).

Like I stated earlier it's not meant to drive every single car out there autonomously at the moment, but it would still be useful now if even a few cars that are several cars ahead had it to alert your car that traffic is slowing or stopped and prepare for it before you would. Especially on a freeway like I live near that has a somewhat sharp bend to the left where traffic usually doesn't back up until around the bend and there's almost always a rear-end accident, so if even one car ahead has V2V it would alert the car you're in to prepare for it. And if it was installed on every GM car it would be pretty good. I could pretty consistently count 2 or 3 GM cars or trucks/SUV's out of 10 in a group on the road and sometimes even more.

The Hyundai system is a "Smart Cruise Control" so you would have to have the cruise control engaged and the driver would have to remember that, it also requires 25 mph or more. GM V2V is automatic and would be tied in with the rest of the safety tech. onboard.

And right now all the non GM or non V2V vehicles would be alerted by the V2V vehicles brakes lights coming on much earlier. It's better than no warning at all.

That sounds like the auto-brake sensing systems already out there. It wouldn't be the lights triggering it but the distance closing quickly.

The emergency auto braking out there now only "sees" the car that's 50 -150 ft. (depending on your sensitivity setting) directly in front of your vehicle that relies on radar and ultra sonic sensors. V2V is an extremely early warning communication from cars several hundred feet ahead in traffic that dictate what is happening.

I'm talking about the brake lights triggering the actual person driving behind to apply the brakes earlier that don't have V2V or another type of EAB safety system. 

Like I stated before I'd rather be involved in the vehicle I'm in and actually drive it, but so many people are not involved or distracted these days so unfortunately we need these safety alert systems for them.

And your V2V system isn't going to know there may be 5 vehicles in between you and the other V2V vehicle braking.

Vehicles with V2V have the onboard EAB system integrated so local vehicle braking is covered and there will obviously be more than one GM vehicle in traffic if they implemented it in all GM vehicles. They are constantly studying American driving habits, it's how they came up with 40 mi. of electric range for the first EREV Volt because a study they ran found that 40 mi. is the average American drivers round trip work commute. So I'm pretty sure GM engineers know more about cars and our daily traffic congestion than you do.

It must be exhausting for you to constantly try to prove people or technology wrong on here...

Toyota is now working on a similar system and V2V would become available for aftermarket as well.

The basics of V2V below.

"Not only will GM share the technology with other companies (at a price), as it did with OnStar, but it is working with other companies to set standards, so that other automakers can use the same basic technologies with completely different equipment. Donald Grimm, senior researcher at GM, said that aftermarket kits were likely as well, a possibility because the system will allow for both active and passive transponders. An active transponder uses GPS to figure out where it is, and connects into Stabilitrak (or the vehicle’s other stability control system) to figure out speed and braking, and communicates both to any vehicle within 300 yards.

How the vehicle to vehicle (V2V) system works

Using vehicle-to-vehicle (V2V) communication, a vehicle can detect the position and movement of other vehicles up to a quarter of a mile away. Vehicles will be equipped with a simple antenna, a computer chip, and GPS (Global Positioning System) technology; they will know where the other vehicles are by communicating directly with them, and other vehicles will know where they are -- in blind spots, stopped on the highway but hidden from view around a blind corner or blocked by other vehicles. The vehicles can anticipate and react to changing driving situations and then instantly warn the drivers with chimes, visual icons and seat vibrations. If the driver doesn’t respond to the alerts, the car can bring itself to a safe stop, avoiding a collision.

The system would replace the long range scanning sensor for adaptive cruise control, forward vision sensors for object detection, mid-range blind spot detection sensors, and long-range lane change assist sensors. GM has the ability to replace all of these sensors with one advisory sensor that will provide all-around, instantaneous traffic intelligence. This promises a better and significantly less costly way of sensing other vehicles around your car while driving.

During a demonstration attended by acarplace in March 2007, GM showed scenarios in which V2V technology can assist drivers. Using V2V communication, the vehicle alerts the driver to vehicles in blind spots with a steady amber light in the side mirror. If the turn signal is activated, a flashing amber light and gentle seat vibration on the side notifies the driver of a potentially dangerous situation. The vibration was enough to get our attention but not a sudden distraction - it was much more subtle than our pager.

Pile-ups on congested roads during rush hour due to a chain reaction rear-end collisions could be lessened. Using V2V, the vehicle monitors messages from other vehicles up to a quarter of a mile ahead. The trailing vehicle warns the driver first with visual icons and seat vibrations on the front and then automatically brakes if there is danger of a read-end collision with the vehicle ahead.

In addition, GM’s V2V technology can warn the driver when vehicles ahead, regardless of lane, are stopped or traveling much slower or any vehicle ahead brakes hard, allowing the driver to brake or change lanes as needed. It also can use rear lights to warn the other driver when the approaching vehicle is moving very quickly and a rear-end collision is imminent.
While other vehicle manufacturers are developing similar technology, GM’s unique advantage is in its ability to leverage or enhance existing systems such as OnStar and StabiliTrak systems to deliver this solution more quickly and cost effectively.
“GM is the world leader in Telematics,” said Patrick Popp, director of GM’s Advanced Technical Work in Safety. “Our V2V technology builds on GM’s earlier Telematics systems to give our customers new meaningful traffic safety and efficiency applications.” "

So back to my original point.

There simply aren't anywhere near enough vehicles on the road for this system to be truly effective.

Not right now it's not, but it could be pretty useful in the future. I didn't and I don't think anyone else on here said that it's in enough vehicles right now. GM has been testing V2V in the Cad. CTS and now CT6 with Gen. 2 Super Cruise.

Dude just read up on it before you jump to conclusions and say "it's useless". And try not be childish with immature comments or vulgar language.  

It's factual that it is useless unless there are enough vehicles using it. 

17% of new vehicles will never cut it.

Like I originally said, AGAIN, unless all of the manufacturers get together and all implement it together, it will be damn near useless.

THAT is why GM is working with other manufacturers and why they want to implement it in several other makes and models.

Did you read anything that I posted above about how V2V works and how GM is working with other manufacturers to make it work even better?
