sign of life

i rode a microbus, i needed to feel the poeple around and beside me, the driver was always making a certain sign with his hand while he is driving , this sign means he is going along the qornashe on the sea side , he shows his way to poeple standing on the side of the road waiting for a transport, the more he makes this sign the more he gains poeple and the more he gains money, money is the most important issue for life, it is the mean of life, so i though that this sign the driver makes with his hand is the sign of life
