The barrier also play a part in this case.

If a 1.5m is given to the cyclist then the car might be occupying into another lane.

Moreover is a huge car, the width is broader.

Best  is to either give way till after the barrier before over taking each other.   

You mean kaw peh and ppl will give you space??

What kind of instant gratification are cyclists expecting?

choy lee doh sor lah (Cantonese)

If you want space you will have to go fight in the LTA office such that the space is given to cyclist on the road. You fight with drivers on the road. What do you get in return? Your mother's genitalia gets the end of it.

So dont be stupid. If you encounter every driver like that you will have to get upset and start an endless argument with him. It's a waste of everyone's time that is not productive. 

Want space on the road? Go look for LTA.

Cyclist assume whole lane belong to him and just swerve to avoid the obstacle nvr check oncoming car. 

Live and let's live, cyclists and motorists shared the road together, instead raise your hands to signal intend to move fist or intend to slow down, give way etc. Motorist just let feet off pedal a bit , all with a hand friendly gesture, thing can be friendly and less provocation on the busy road.

During pandemic driving with mask on, it is not hard to show courtesy of a friendly face by acknowledgement of head bow or wave of hands. It is an International language known by all. Peace 

Almost no traffic on road also can like that

So when cyclists run red lights, do they ownself scold ownself? 

It's your freaking life. You expect others to look after it for you?
