Yellow box salah.

Just ask yourself: who has the right of way? Just because the taxi cannot see the motor means he can ram the motor?

If the taxi driver was driving on our B road and overtake a lori balak but cannot see the motor from opposite lane, that means he can langgar the motor too?

You go straight. A car makes a turn and you hit the car. Car driver says you are wrong because you did not try to avoid. So, are you wrong?
It's like saying the victim of a knife attack is guilty for not evading the attack.
The taxi failed to give way to the biker which had the right of way. You want to cross the road, you make sure the road is clear. Is this hard to comprehend?

All said, I still think the biker fails in defensive riding. I think we both can agree on this.

This agree.
I said the biker has the right of way because he was going straight.

I did not say biker is not an idiot for not expecting the unexpected. I think there are a lot of idiotic bikers who think they are Mr. Invincible - this is coming from someone based in "island of salah LGE".
