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

You need to consider the case of an emergency stop - front car suddenly
halted by a seized wheel, lightning, crashing into a tree that has
fallen onto the guideway (and that hasn't been spotted by its own
forward sensors) etc.

AIUI, the computer system reacts to any such unexpected change of speed
with an emergency stop command to all vehicles. At the projected speeds
and headway, there is ample time for the car behind to stop before
hitting the halted vehicle.
