I've been told that RTO autobraking can be quite painful (more than Max Autobrakes on Boeings). Your harnesses dig into your shoulders causing pain, so you can imagine the passengers' bodies/heads flailing about under RTO braking.
Presumably you don't want this kind of braking for every rejected takeoff, only for those rejected takeoffs in the higher speed range where remaining runway length/reaction time and the potential for greater injury is an issue.
