He's an insanely powerful, fast, intelligent creature with highly sensitive sensory organs, access to highly advanced alien tech and a cadre of connections in the superhero community. Shouldn't he be in the territory of kid with a magnifying glass when compared to Joe Blow.
Like say he's going out to get a pizza from his favorite pizza joint but he doesn't feel like signing autographs and explaining why he didn't cure cancer for the billionth time. So he just goes out and borrows Bruce's emp mask (or builds his own), conjures up a fake face, and VOILĄ no hagglers. Or he brings along a psychic friend who scrambles everyones perception of who he is. Or Dick tags along and he hypno's everyone into not knowing what they're looking at. Then somedays he's just like whatever and the kids on the street run up to him and he flies them to Versailles and back for fun.
