Colder weather brings ice on windshields. Though it seems people can't shake the briskness from their bones fast enough, nor want to scrape their windshields, I've seen many just start their car, then head back inside while it warms up. You're not supposed to do this.

According to the Washington State Legislature, this is illegal. It's perfectly A-OK is you want to warm up the car if you're still in it. There's no law against that. There's also no law against waiting for the windshield defroster to melt the ice from your windows in lieu of scraping it. But if you're not near your vehicle when the keys are in the ignition, you're breaking the law.

No person driving or in charge of a motor vehicle shall permit it to stand unattended without first stopping the engine, locking the ignition, removing the key and effectively setting the brake thereon and, when standing upon any perceptible grade, turning the front wheels to the curb or side of the highway.

Not only could someone steal your vehicle, but if something were to happen, you'd still be liable.
