You can never be to sure, and as i can see you have a kid, personally, id go over and speak to him, and make it very very very clear, that A he doesnt own the street, you have a right especially as a resident to park close to your home, and that your considerate enough to not inconvenience any neighbors, and that immature behavior will not be tolerated(intimidate,scare what ever it takes, he in all reality put your family at risk) moving cars is one thing, endangering you and your family is another, or, stoop to his level, and steal all his lugs, and stack his tires behind said vehicle that outa make it clear, personally if he had done that to me, i would have written him a note to piss him off, call him a pussy or what ever it woulda taken to get him to start something and wipe the floor with the guy. I dont care about what any of you say about that, a mans family is a mans family, and you dont endanger that!!!
