People complaining about a recent increase in harsh braking events. New airbus aircraft have an autobrake function called BTV (brake to vacate), it seemingly does nothing until very close to the exit you have preselected, it then brakes very harshly to make the exit. As someone who flies a new airbus, I hate it, but we are told to use it as it saves costs as reduces brake wear, it also reduces runway occupancy times. Unfortunately I think you will find it becomes the new norm on new aircraft and so you will notice it more and more.
