You don't have an engineers certificate, so in short, it's not bullshit. Maybe they shouldn't be picking on people but if you had an engineers certificate you would of driven away untouched. At the end of the day that's all it comes down to is having the paper work and legal mods. Sure, I don't have an engineers certificate and have modifications that would be defectable. If I get pulled over and get defected, I won't be happy, but at the same time its my own fault for not having it engineered, simple as that.
If you're that worried about being defected maybe you should spend the dollars on an engineers certificate and you won't have this problem
