Hmm, and then again...

Israel was pretty close to being overwhelmed - it was luck (or talent) that changed the tide in the golan heights, not the nukes they had but didn't use.

This is old news, I remember seeing a thing like this three or four years ago.

To answer your question, no, cows generally do not get rowdy in the machine, as it is in their best interest to get milked, as they experiment the breast-equivalent of blue balls.

Another cool feature is that if one cow is quarantined (for instance, giving antibiotics means that you cannot use the milk for a week), it will still be allowed in the machine, still milked (otherwise it will get blue balls), but the milk will just be discarded based on the ID on its collar.

The overall result is happier, healthier cows, and greater yield, compared to standard twice-a-day milkings.
