Comment on Self-driving Volvos cover 200km of busy Spanish motorway

This is a great notion for long distance road trips. It would be pretty nice when cruising cross-country to drift in behind an 18-wheeler and then read a book.

I think we'll get fully autonomous vehicles before this type of thing becomes common, but it's pleasant to envision a future where cars on the freeway form little spontaneous communities, with lead cars broadcasting "hey I'm headed here, hitch a ride" and others falling in behind.

Yes, I know there are a million ways a griefer could cause problems. Yes, I know that driving a car on the freeway in the middle of nowhere is one of the easier scenarios for a completely self-driven car, and no lead is necessary. I still think that self-organized caravans is a cool notion.

I was little surprised at first about: "three cars behind the truck at an average separation of 6m". But this is probably an idea to lessen drag. It doesn't matter what powers our cars(gasoline, biofuel electricity), less is less, and we need all technology that can do it.

This is probably very important step towards self driving cars. Because some kind of commercial product will bring loads of money to the field, even if it's very basic.
