being linked into a virtual train

They will save on space required between them when for the portion of
those independent journeys that they are all going in the same
direction for a distance and each individual car is closer than would
be safe with manualy driven ones ,
Actually, no. One of the current problems facing developers is the fact
that driverless cars are actually slower to react to emergencies and any
unusual events.
no thinking time from human drivers
though it could well seem strange to present drivers who on the whole
get uncomfortable when people Tailgate.
The gain would be by greater through put on roads so if those cars are
not delayed by congestion that would have occured then they will have
gained something .
To get maximum through reduce speed, down to about 5mph.
I would suggest taking a train on west coast main line and look out the
window as the track runs alongside the M1. Then imagine another 3000+
cars pumped onto the motorway.
Now Hugh as given me the proper term have a read.

Like much of the driverless car concept it may never come about or
happen in a different way but it is one mode of operation that is
being looked at.
