There are lots of groups like that. Some drive through Richmond occasionally doing doughnuts in intersections (here's a fun one from last year: https://www.carscoops.com/2022/02/police-stop-car-club-plan-to-takeover-richmond-virginia-for-donuts-and-drifts/). There are drag racing groups, there's the old cannonball run across the country - tons of car groups that love to skirt the law.

Then there are just the tons of unaffiliated drivers who speed, drive while texting, DWI (it was JUST a few beers!), hop into the shoulder if there is traffic, etc. Ignoring the law and other people's well-being doesn't require a group affiliation! The potential for damage is significantly higher from a single driver on a highway texting than nearly anything a cyclist is capable of.

I am all down for you wanting to advocate for better adherence to infrastructure and legislature, but trying to call out the bullies as some kind of cyclist-only anomaly is weak.
