Why Motorcyclists Only?

Did you read today news? It mentioned that the motorcyclists were warned of road ban by our smart Minister if they continue speedy at highway!

My question is why only motorcyclists? Why not express bus driver or car users? Do you really think that those car accidents are caused by motorcyclists? I know sometimes those motorcyclists did ride crazily on the road but still not them the one who solely cause road accidents. I only think of express bus driver who drive crazily at high way. See, when we travel to Kuala Lumpur, driving our car at 150-160km using express lane, those express buses still able to overtake us. You go figure out how fast they drive then!
