The busses in our area actually have GPS or some sort of landmark system where a Text to Speech generator will call out the intersections without the driver's intervention. Guess this is a good way to get around it, especially since inside the city, it would get pretty old having to call out intersections every 30 feet.

Sorry to dig up an old thread but I thought I'd add something to the reply. I was a machinist for many years and when machining most metals, especially hard steels, we'd use a special water-based lubricant/coolant. It kept the tools sharp, the workpiece cooler and actually helped the tool cut more aggressively.
