I was driving along the highway, on the left most lane (that would be the right most in the US and other countries that drive on the right side of the road).
I was driving casually, minding my own business, when from the rear view mirror I could see an old Nissan sedan closing in on me. I could also see that the occupants of the car - four or five of them - were excitedly jostling on their seats, waving their hands about, and pointing towards my 4 x 4.
