I'm not happy with the Quai-Chang-Kane-like scene where she saved a dozen children, then was reviled for defending herself from the asshole driver who attacked her. The idiot drivers were the ones to be angry at.
Well, actually she had no need to defend herself, because she's about a thousand times stronger than he was and he posed exactly zero threat to her. So in that context, her action was rather excessive. We're all extremely fragile next to her, so if she can't control her temper around us, then we have reason to be afraid.
I agree that's an issue, but I'm still not sure I buy the kids and everyone else freaking out about it the way they did. The guy was clearly being belligerent and was inches away from running over a bunch of kids, so if anything people would probably be
cheering Supergirl for beating the guy up a bit.
Although I suppose it is a good illustration of how much a video can be misinterpreted if you don't know the full context behind it...
Of course realistically, if a car had been stopped THAT suddenly the driver wouldn't have been in any condition to get out and threaten Supergirl. He'd likely be either unconscious or dead with his head sticking through the windshield.
