A stunning new discovery: Every car has what I've coined the "engine thermostat." It informs the driver of the temperature of the car's engine. For example, on a cold night such as this, the "engine thermostat" is under the C(old), indicating that the engine has yet to be heated. However, while the driver proceeds to drive, the "engine thermostat" reaches somewhere in between the C(old) and the H(ot) letters, thus indicating that the engine has heated up to that level.


Fascinating.
