Like I said before, SPB, there are 'brain dead' in every group. I doubt very much that the proportion in cyclists is any higher than that in pedestrians, dog walkers, mobility scooter riders, drivers, nuns on roller skates or penguins on skateboards. Not whataboutery or making excuses. Just putting things in perspective. The other thing of course is that inconsiderate cyclists rarely cause death or serious injury. The same cannot be said about drivers. I tend to save my energy for the more serious transport abusers!
