I was sitting in my Prius at an intersection in Westchester County, NY. A big truck got stuck trying to make a turn. I missed about 4 lights before the truck was able to move again. For most of that time, my Prius wasn't costing me a cent of gas, because the internal combustion engine ("ICE") had automatically shut off, and the electrical engine had taken over.
Now, sure, I could have turned any car off, easily. But how many times have you ever really done that, sitting at a light for a long minute? Never, is my answer.
And when you drive in the city, you're stopping at lights, and sometimes stuck at them, almost as often as you blink. And every time that happens, you save a little gas money - that you otherwise would have spent, for literally moving nowhere.
I heard today that Toyota is shutting down an SUV plant in the US, and opening up a Prius production plant. Way to go...
