Mine has been scaring me recently.
Not too long ago we had an incident. At a 'T' intersection with a stop sign, my wife slowed down, but kept rolling through the stop. The driver that was waiting got visibly upset as did I, shouting that she'd just ran the sign. My wife seemed to think it was no big deal.
Well, this morning we were in the left turn lane waiting for the light to change and another car was in the oncoming lane. The light turned green, but it wasn't the left arrow, meaning my wife had to wait for the oncoming traffic. She started turning left in front of the other car! I shouted and she stopped, but now I'm concerned about her driving ability. Maybe it only happens when I'm in the car and she's distracted...but forgetting the basic rules of the road?
