Yeah, but in my case, there were 5 cars each side, I let them all pass. I started to cross the street (a quite wide one), and during that a 6th car came to the stop and decided to actually stop, and then start, even with me in front of the car.

Personnally, to cross a 4 way stop intersection I simply follow the road code:

Let's suppose the path is clear:
Car A gets to the stop
Car B gets to the stop
Pedestrian C gets to the stop
Car D gets to the stop
Car E gets to the stop

The road code says they have to cross in the A B C D E order. But in practice it's A B D E C.

Now in tonight's case it was worse:
Car A gets to the stop
Pedestrian B gets to the stop (Me)
Car C gets to the stop
Car D gets to the stop
Car E gets to the stop
Car F gets to the stop
Car G gets to the stop
Car H gets to the stop
Car I gets to the stop
Car J gets to the stop
Car K gets to the stop

So the order should have been : A B C D E F G H I J K. But it was A C D E F G H I J K B. Now the problem was that a 11th car got there AFTER I was crossing, and decided that it could roll on me anyway. (Well, not really, but you know how some car kind of try to accelerate toward you to make you go faster.)

Personally, I also get kind of bugged by pedestrians that cross the street the second they are there. But as a driver, even if I'm not "really" supposed to, even if I was there before, if there are more than 100 KPH winds with blizzard, I mean I'm in the heat of my car while the other is facing the wind getting his skin stripped off his face.
