At the carpark, the lot was in between 2 roads. However, to enter the lot legally, you would have to be on my side of the road, as the other side was blocked by the chevron marking on the road.
On the other side of the road, an ang moh driver with 2 ang moh passengers entered the lot despite me driving in. At the same time, I was entering the lot from the legally right side of the road. As I didn't want my car to get hit, I drove out as the driver did not get the hint that I was going in. I waited for him to park, and later horned. He came out of the car and I said, "you are on the wrong side of the road." He had the nerve to reply, "so?"
Chevron Markings
"Diagonal white lines (hatched markings) bounded by broken lines may be used in the centre of the road to separate opposing flows of traffic. They are often provided at junctions to protect traffic turning right. They may also be used on the approach to a central traffic island or the startof a dual carriageway." - http://www.ukmotorists.com/marking_signs.asp
Ang moh
"A Caucasian or a white person." - http://www.urbandictionary.com/define.php?term=ang+moh
