Molotov abandoned car
Realize that I did not take driver’s ed. in school because I wasn’t as inclined to be driving as all of my older classmates. Nonetheless, I took my driver’s test, passing both the written and driving tests on my first try. Nowhere in my memory did the driving manual say anything about hanging a rag out of the driver’s side window when abandoning my car.
I’ve seen a few cars lately that have done this. They were left in odd places, too. I suppose that there must be some reason for leaving a t-shirt or a towel, usually white, rolled up in the driver’s side window, otherwise not so many people would do it.
