Totally different technology that involves ZERO v2v communication so this is by no means a leg up.
As more car cams and sensors etc. come online, we or our cars probably will start to get pretty up to date warnings on potholes, debris, icy spots, etc. and maybe even advance warning on moving hazards detected by other nearby cars.
Another thing you won't see very soon. There's no revenue stream to fund putting expensive sensors on cars that can't drive themselves solely for the purpose of warning other cars. And since v2v communication has not even been developed it will require allocating bandwidth thru the FCC etc. The process of establishing the communication protocols will be lengthy and will include significant input/negotiation with all major car manufacturers including no-doubt some international debate as well. The process has barely gotten of the ground as the NHTSA has only initiated a comment-period to begin the process (in 2017) and is still "reviewing" the comments having made no rulings or even tentative positions on resolving the problems raised including privacy concerns etc. that will continue to be debated along with possible opt-out choices for drivers. As always you'll find aggressive people with an agenda or just the desire to get readers telling you it's a couple years off. I think longer myself but probably within a decade.
