Can I have somebody arrested for standing in front of my car and not letting me leave

Yes you can. Your personal freedom include the ability to travel where you choose without being restrained by someone else. When someone else restrains you or prevents you from travelling, this is punishable as a crime, known as false imprisonment. The crime of false imprisonment, sometimes called criminal restraint or criminal confinement, occurs when one person unlawfully restrains someone else without the victim's consent.False imprisonment can also be punished with a fine in addition to jail or prison time. Misdemeanor fines usually do not exceed about $1,000, while felony fines can be significant, exceeding $10,000 or more. If you are the victim of such a crime you should call the police at the time it is happening.
