I don't think it's lack of care for the most part...it is confusing.
So we all learned the whole, "first arrived" technique then the "driver to the right"...and I think that works fine during off peak hours of the day.
However during school pick up, morning rush hour, and afternoon rush hours, this doesn't work AT ALL. But our driving protocol expects it still to work.
Instead it should be that the two opposing sides going straight goes, then the two left turners, then the opposite straights, then the opposite turners. Efficient, everyone knows what they are doing. And this is how it works a lot of the time. But the people who try to follow the drivers Ed protocol mess that all up. They don't go when the car going straight next to them goes. They wait til some awkward time to go, then honk and flip people off for not knowing what the eff they are doing!!
See #4 below. Dumb!
1. If each car arrived at a different time, then they leave in the order in which they arrived. To repeat: Leave in the order in which you got there.
2. If two vehicles arrive at the same time, the driver on the left defers to the driver on the right. In other words: The driver on the right goes first.
3. If two vehicles arrive at the same time and one of them is signaling a turn across the path of the other, then the one who is not turning has right of way.
4. If you had to wait in a line at the intersection to get to the stop sign, this does not change anything. Each car stops and then follows the above rules as if no one else had been in line before him. (In other words, you can’t conclude that you were there before the person at the other intersection just because the car in front of you was there before him or her.)
5. If you are at a T-intersection with a 3-way stop, the vehicle that does not have to turn has right of way.
