We know that after Pydna, L. Aemilius Paulus was stated to have nightmares of pikes and Livius' description of the battle gives the impression of much higher casualties than he actually reported.

At Magnesia, it doesn't even seem as though the Roman infantry came into contact with the pike phalanx, which had rather quickly formed itself into a block realizing it's left flank was compromised. It was the Romans' ability to frighten the elephants that did the trick. Even then, it seems that the Argyraspides on the right might have been successful against the Romans there.

At Thermopylai, the phalanx held off Roman advances time and time again until the rear guard of Aitolians ran from their emplacements allowing Cato the Elder to appear in the rear.

The fighting at Kynoskephalai is another example. The Makedonian right was putting up a tough fight, which would likely have resulted in victory if not for a Roman assault on the flank. But, those Roman forces didn't suddenly appear because of superior mobility: they managed to assault an unprepared Makedonian left wing and chase them off. Any enemy would buckle at an attack from the flank regardless of perceived flexibility (i.e. Pharsalus).

The point is that when met head-on the phalanx could usually push an enemy back. For the Romans, they were given a number of opportunities, but would do their best to avoid the phalanx straight on unless such opportunities presented themselves (e.g. routing of the Seleukid cavalry at Magnesia, rough ground at Pydna).

And as to Roman brutality, lets not sell the Makedonians short either.
That doesn't justify the fear trait rather that people don't run straight into pikes and pikes can push units by their wall of spear points. They can do this quite well as it is.
