Kids pick on weirdos, so if there are some bad kids around there and they think he is a weirdo and know that he is fussy about his car, they will target his car to get a reaction from him, wasnt suggesting he should care too much what the locals think of him but he might care what actions they direct towards him as a result of those opinions.And who gives a damn about being the "local weirdo" washing his car in the carpark?
