The most infuriating type of reckless driving for commercial vehicles lately...

More than anything else, the most infuriating, hopeless, and trashy driving behavior is when everyone else is waiting in line fairly to turn left or go straight, but a single city bus driver moves all the way to the right side in a very obnoxious way, cuts to the very front, and then attempts to turn left. Is this behavior something city bus drivers should be allowed to do for the rest of their lives?
If this is just left unchecked, I feel like they will eventually try to cut to the front by crossing into the left lane, just like they did 30 years ago.
Honestly, I felt like beating them up—not just the other drivers nearby, but even the passengers watching would agree (I know this well because I've experienced that bus firsthand).
In my case, when they cut in front of me, I honked my horn extremely loudly for almost 20 seconds...
And in cases like this, even if the passengers shout out loud and curse at them, is it possible that the bus driver will simply ignore them and act even more defiant, as if saying, "If you don't like it, leave"?
