The "good/neutral/bad" DND axis implies moral intent, not necessarily outcome. A stupid person doing something insane for a reasoning that is generally understood to be morally good can be seen as "chaotic good." Hence why a lawful good Paladin can maintain their lawful good status, and their divinely derived abilities, even when they're doing things we may consider evil, like executing a youth for breaking a law, so long as the Paladin (and the divine entity) strongly believe that it's for the greater good of the law and society.

In this case, the guy thought he was preventing people from using their phones while driving, which is a good thing, but he was too dumb to realize it would have negative consequences apparently.
