Sure, there will be some fancy expensive cars with it. But look around at the cars on the road.
I have. The average age of the American car is 11 years, and that's an all-time high. They're putting fancier and fancier tech into cheaper and cheaper cars because it doesn't cost them that much and it's a way to compete. V2V works best when it's in the most vehicles, so they'll want to put it in a lot of vehicles. They just won't put the HUD into a lot of vehicles, they'll want to charge you extra for that.
