This idea has been around for a long time, it can sneak past the passing cop most of the time, but it's not 100% legal. If you're on the street parked, they can/will give you a ticket if they notice it. The only way to avoid a ticket is to just follow the law, no matter how retarded and ridiculous it is. The car I drive every single day and park with NFG is a car that is 100% legal. My other two cars on the other hand are not. That's why I have 1 legal car and just take the risk of tickets in the others. It is what it is, we live in a shitty state with a fuck load of debt, they can and will make as much money as they can on people trying to be crafty. We should all be ashamed for living in IL.
