That thing with the rear wheel off is not a canard. I once did it on my way home from Maine in a '65 Citroen ID. I had a blowout at the intersection of 91 and 95 and pulled over. I did not realize until then how clapped out the car was. Not only was the underside too rotten for the jack but the spare tire was dead. I stacked up a mess of stuff with the car elevated, retracted the wheel, removed the dead tire and wheel, reraised the car, removed the blocking and drove home. Fortunately, the car belonged to the dealership and not me. [I was their sales manager at the time.] One of the many things which made me appreciate the beauty of Citroen automobiles.
