Why aren't these car drivers increasing their speed when overtaken by the Kawasaki Ninja?

In these clips I found from YouTube, I see this Kawasaki Ninja ZX-6r on a South Indian highway going full fast and it's overtaking so many cars but why aren't these car drivers increasing the car speeds to overtake the Kawasaki back? Don't they feel their ego hurt by getting their cars get beaten by a motorcycle on the highway?
