If you’ve always used power assisted brakes and you’re not expecting to have to press really hard on the brakes it could easily lead you to rear end the car towing you if it stops suddenly. Also, without power assisted steering, modern cars are surprisingly difficult to control.

Ye especially the steering. Small steering wheel and lower gear ratio on modern cars makes them kinda unsafe in the event of power steering loss.
