Several Chicago, Illinois food truck owners filed a lawsuit against the city today. The suit seeks to shoot down rules that require constant GPS monitoring of their trucks and force them to stay 200 feet from any business, like a 7-11, that sells food. The rule puts the Loop, Chicago's downtown area, practically off limits.

As Reason's Baylen Linnekin wrote in July, there is precisely no public health and safety justification for the law, which Chicago aldermen passed by a vote of 44-1 last summer at the behest of non-mobile establishments.

The Institute for Justice,* a libertarian public interest law firm, which represents the food truck owners, has produced this whimsical video highlighting their clients:
