I believe its mandated in the US to have TPM mounted in the wheels in the form of a pressure sensor. Whereas in Canada we do not have that mandate (and quite possibly pretty much the rest of the world) The ABS system is used in our case as a FTM. (based on individual wheel speed or rotation). Not sure which is best. I would think an actual pressure sensor would be quicker to warn the driver of a tire issue though.
