Fair enough, I see your point - and yes, I suppose the Victoria line

That seems perfectly possible - they could lower the rate of change of
deceleration, without significantly sacrificing the magnitude of the
deceleration.


You beat me to it! The rate of change of acceleration [1] is known as
'jerk rate',

Third, surely?
