The closest call I've had was one block from our home. I was at a stop sign on a residential before making a right turn onto another 2-lane street with a 35 MPH limit and double yellow lines down the center. I looked right, then left, and then started to pull out as I looked right only to see a car on the wrong side of the road doing about 60 MPH.
I also passed a wrong-way driver on a freeway earlier this year. Luckily there wasn't much traffic and I was in the slow lane of the 3 lanes so there was an extra buffer between us. I saw cops tailing him down the other side before I could dial 9-1-1 and he crashed into another car not long after he went by me.
