I would advise you not drive a homemade fruit car around your town if you are this terrified of the attention it will bring. He clearly said in the article that he enjoys the encounters. He is doing this on purpose.
Him enjoying the attention doesn't make the actions of the police right or just.
He enjoys the attention, they are abusing their authority, Both things are true.
It's perfectly reasonable to question whether that vehicle is street legal when it passes by on the road. It would be my first thought. It looks like it's mounted on a boat trailer chassis, and the windshield appears to have questionable effectiveness at high speeds. Pulling him over to ask about it seems like they are doing their jobs. Especially when I am also a driver on the same road.
