What speed is considered reckless driving in California?

I want to get rid of my car loan as fast as possible. Is it a smart move to put more money toward the monthly payment each month to get out of debt?

I had to get diesel fuel for my friend's truck when they ran out of gas. Some of it must have leaked onto my carpet, because now my whole car smells like a gas station! How can I get rid of the smell?

My son drew with a crayon on our car windows. Don't get me wrong, I love that he's a budding artist, but I'd prefer he kept his work confined to more traditional mediums. Unfortunately, it's so waxy that I'm not sure where to start with cleaning. How can we get the crayon residue off?
