The fallacy is that you're now claiming that obnoxious idiots are not "car people". According to you, people that "love cars" are only "car people" if they have money and like "fancy" cars. Idiots that get exited by tuned up BMWs are not "car people".

Which of course if false. All of them are "car people". Rich car people driving expensive cars are the minority. Majority are the loud idiots. Of course you're looking down at them and don't recognize them as part of your group. You're "superior" because you go to car shows, not parking lots outside of town. For me you're all the same. Silly people getting exited about silly machines. Your distinction is meaningless.

P.S. And of course I know plenty "car people". Everyone does. You're not some secret society. We went to school with "car people" and we work with "car people". The roads are full of you and we all see bunch of you every day.
