This is to X22-XXXX License Plate Black Prius driving in Chicagoland today. PLEASE do not try to maintain electric drive (or fall asleep at the wheel, whichever) in the middle of 5 pm rush hour traffic! This is very dangerous. You were weaving all over your lane, and on at least one occaision, about 2 foot into a lane next to you, which had another vehicle in it side-by-side. Just drive your Prius until you figure it out. If its the AC control that you cannot work, roll down your windows!. Something was seriously wrong with the action of your car on the road today! And from my vantage point you appeared to be nodding off. If I was a state trooper, I would have pulled you over for sure!!
