Is it illegal to perform Chinese fire drills if there is no one behind you?

Yes, Chinese fire drills are illegal no matter the circumstances. The driver of the vehicle is responsible for his or hers passengers actions and as the driver if you allow your passengers to "do" a Chinese fire drill you are participating in reckless driving. Reckless driving tickets are hefty no matter what city, county, or state you receive the ticket in. The best thing would be to seek thrills by doing other activities.
