Has anybody read Bedards article in the current Car and Driver?
He talks about a new 'fund raising' style in California (also AZ). The authorities film cars in gatherings like parking lots, known racer hangouts, etc.
Then they pop the owner (driving or not) with impounds of the cars. PB says tickets can run up to $1500 or more to get 'your' car back! They can also tow you for not carrying your license or current registration. They say they don't bust the gatherings anymore because it leads to 'high speed, unsafe exits' so they came up with the filming.
What a scam.
