Want to see how Malaysian drives? Part 7

In this part of the video clip, I would like to show another express bus driver's arrogant attitude on the road.

First, we were tightly tailgated by this bus from Utama Ekspres. It tried to overtake us although it is impossible at that situation because it's on a trunk road with double lines.

Next, we patiently wait for the heavy vehicle in front to pull to the left hand side, and we will overtake soon after the Proton Saga in front of us had finished done that. But just before even the Proton Saga finish overtaking the lorry in front, the express bus impatiently cut in from the left.
I believe what had happened was just tips of the icebergs of bigger vehicles trying to bully the smaller ones. The drivers here in Malaysia are not trained to drive politely.

What do you think could improve the attitude of Malaysian motorists?
