There is an increase of such inconsiderate idiot on the road these days. They are impatient, rude, ruthless, brainless, arrogant, etc. You might be wondering where's the authority in-charge of such matter, I can answer your question that they are hibernating in their air-conditional offices, they are not willing to expose to sunlight, they can be easily melted off if encounter such barbaric drivers of Singapore, if you know what I mean.
I seldom drive these days, I hate driving, I hate going out. Singapore is getting more and more scary, there are a lot of cars, especially a lot of bad drivers and a lot of unfamiliar roads, more and more roads (look at the our map you will know what I mean). There are a lot of people; hostile people with hidden psychological problems walking down the street. It is no longer a place I am familiar although I have been staying here for so many years since birth.
