Yes, that’s correct: Vehicle-to-vehicle communication / technology is being mandated by the US Federal Government. Unlike many non-interoperable systems on the market currently (most notably, Mac vs. Windows / iOS vs. Android, etc.) supra-imposing this mandate (in theory) is a good thing… as long as said vehicles don’t have a feature whereas they’re focusing on updating their Facebook status vs. driving!
