Speedy Cabby

Today, my cab driver wildly swerved in and out of lanes and almost sideswiped a guy on a motorbike. So, I politely asked him to "cha cha noy" or slow down a little, but he laughed and kept driving like a madman. Had it been a Nascar race, we may have won, but there are no checkered flags on Thai highways, only checkered patterns on the interior of this cabby's vehicle.
