It's a table. You can eat food while parked, without having to hold everything in your lap.

This should be obvious but DON'T USE THIS WHILE DRIVING. It completely blocks your ability to steer properly, and you'd look super dumb to the police officer having a TABLE in your car if you got pulled over with this inside. Just use it while you're parked like at the drive-in theater, or to go get tacos 30 minutes from your house so that you can eat them before they get cold.
