I saw something I thought was odd yesterday whilst out in the car on the M42. One car, a red Mini, pulled out in front of another car, a black BMW. The BMW driver braked and sounded his horn in one short blast, followed by two long blasts. The Mini driver replied with, one long blast, one short, another long blast and finally another short blast. The BMW driver, obviously a tad miffed, then proceeded to tailgate the other up the road, repeating the same sequence of blasts. Whilst thinking what a pair of tossers, it occurred to me it sounded like Morse (code, not the TV detective) with the BMW using the code for "W" (w*nker perhaps) and the Mini driver using the code for "C". Could this be another way for drivers to express their irritation? Suppose it would make a change from the odd angry toot if it was.
