Yeah, 30mm is overkill for a Hilux but you don't want to show up with a cluster of .50s on the day they decide to drive the BMP to work.
That said, antitank weapons are good enough that well trained and equipped infantry should basically laugh off a BMP (or any other AFV) in most situations and there's always bombs and missiles.
