We visit USNA often as it's nearby. I often see cars parked illegally. One time I saw a Jeep with emergency lights on, parked at a marked No Parking area just outside of their Barracks for about 20-30 min. Then a couple students came out and drove it away. I didn't see any kind of emergency except the parked spot was closer to the dorm. I don't know how discipline is like in USNA, but I think this kind of stuff is not often seen at West Point.
Sometimes I think about why West Point has a little bit lower average SAT's than USNA, but ranks higher than USNA in most ratings. The difference in discipline might make a difference.
