A lorry, driving beside me, was trying to overtake to my lane. Being a little too close, he wind down his screen, took out his hand, and gave the hand signal (Position 1).... Seeing his signal, I slowed down to let him cut. And he slowly inched his way in. After cutting in, he pulls his hand in and put it out again slowly in a circular motion. His hand ended in position 2, followed by a small waving motion, which meant 'Thank you' I guess. Then he retracted his hand a bit, and took it out again, this time pointing his second finger to the place he is turning to. Wonder what he did that for, and I am sure it was not the third finger. Maybe this guy was just so courteous, that he wanted me to know where he was going. If I stayed longer behind him, I might be able to see more hand signals. But too bad...I had to turn out too.
