Barack Obama probably didn't intend it, but he has started a movement with his calls to improve vehicle economy by properly inflating tires. Now California is going to consider regulations on tire inflation, and having the police check tire pressure and issue tickets if tires are not properly inflated. This won't save much fuel, but it may raise some money for the state. Here is the article:

It is curious to me that liberals always complain about the alleged restrictions on individual liberty they claim conservatives support, like not recognizing "gay marriage," while ignoring the attacks on freedom of speech and liberty by liberals. Liberals want to tell people they can't smoke cigarettes (but marijuana is OK), fast food rrestaurants are banned, etc.
