Here is a video of a guy that tried to automate a grinding machine by installing an electric motor. Initially the movement was very unsatisfactory, it was not smooth, or very jerky. He then received an upgraded motor that included a “jerk control” feature and the movement of his machine became smooth.

It came as a surprise to me but it seems like jerk is something that can be felt in real life.
