I feel so uncomfortable driving when biker’s beside me driving too. Some of them are annoying because they try to fit in no matter how small is the space of the road most especially during rush hours. One time there’s one guy in a motorcycle driving so fast and trying to beat everyone on road without wearing his helmet. He just hang his shoei helmet on the side. He was caught by the police disguising to be just ordinary driver at that time. What a stupid guy. I think he had penalty. Whatever his reason, he must be responsible at all times for his own safety.
