averagely, if you have been driving here for a long period, you will just ignore these things. Time will come that yes, you'll get upset, but what to do, you can't change their attitude, if you confront them, it will just be trouble.

Best to do if you can't help is SHOUT and RANT and WHINE inside your car, BUT NEVER open the window. So you released the stressed and be back to normal.
