We already have this capability in the world ... it's called a "Bus" ... it transports 54 people 'in unison' while the passengers can read, do their nails, work on their laptop or just view the scenery, and far far cheaper per mile than 54 cars rolling along together, too.
This new technology may work on the open highways, but let's see it go through a roundabout in busy London or see what happens when one (or more) of the "wirelessly connected" cars gets stopped for a traffic signal, etc. We have moronic traffic signals here that only allow two cars to go through on a green before it changes to red, and then there is a 90 second wait for another green ... meanwhile the "wireless caravan" can be several miles ahead somewhere.
And just 19' between each car? That's very unsafe and doesn't allow for a good safety margin ... and what happens if this 'caravan' of multiple cars approaches a very slow moving lorry going uphill, and there is only room enough for one car to pass it at one time?
Too many questions - too many possibilities haven't been answered yet in their study. Besides, the car is for individual and family travel - not another place to surf the internet and read books - we can do that at home - or take a train or a bus.
My kroners worth, anyway.
