V2V stands to be fucked up for a multiplicity of reasons: shitty engineering, corporations trying to monetize it, and privacy issues
Bad engineering and monetization efforts ought to only foobar the 1st generation products.
Remember..... before Ethernet, we had DECnet, and many proprietary network protocols designed to help corporations attempt to monetize it by making themselves the patented standard everyone would have to buy.
Note we no longer use all those protocols, but the Internet still became a reality.
Corporations trying to monetize don't necessarily stop an idea that is good enough that has the right community backing it who isn't willing to put up with vendor crap.
By every indication, people only say they care about privacy issues, but when it comes to actions in the real world, the vast majority people ignore privacy or will happily throw it away for convenience, free products or services, enabling them to interact with more people, or more fun toys.
