Also, computer-control of the entire system
means that if the vehicle in front is braking,
the one behind can react within a fraction of a second.

I would hope that the vehicle behind would start braking first, and only
when the brakes on that are known to be working would the vehicle in front
start braking.

That won't work, because by the time the hundred vehicles behind the lead
one have gone through that process, the first will be well past whatever
it was braking for.

No, because it will be braking for a station at which it has known for
several minutes that it would be stopping.

And this is going to work /how/ for child-in-front?
