Idling for 10 seconds uses more gas than restarting the car

Ok, this has absolutely nothing to do with the law, but I was so amazed, that I figured most other folks don't know this either.

In the winter, many people idle their car engine after starting it up because they think it needs time to warm up. Not true! Today's fuel-injected engines don't need a warm-up period, and idling for long periods can lead to excessive engine wear.

Worse, cars idling for more than 10 seconds use more gas and create more global warming pollution than simply restarting the engine. Surprised? It's true - the 10-second rule has been proven empirically.
