Why do people feel the need to breakcheck anyone? And trucks at that, like they couldn't just keep going or just be unable to slow down enough and hit these idiots...

And why check for breaks? I mean, brake checking, sure, gotta make sure your brakes work, but taking breaks involves getting off the road and pulling over.
I break check people when they're on my ass and I will be breaking soon. Because if I start actually breaking I will definitely be in a wreck.
I don't brake check people, but I do flash my brake lights a few times if someone is tailgating me. That generally makes people realise "oops, sorry, I was too close". If they ignore that I slowly turn the cruise control down until they'd rather switch lanes and zip off. Funny how I'm only tailgated when there is plenty of space in the passing lane to the left of me.
The brake checks that the assholes do are when they actually brake to have near-collision vicinity to trigger collision warnings/autobrakes on trucks and busses, or to really rile another car driver up/collect insurance. But they forget that many people nowadays have dashcams (thank you Russian insurance companies!).
Don't brake check, just glide. Brake checking is more likely to cause an accident. Just naturally slowing down won't.
Plus it really pisses them off.
