i was on the pie (tuas) during evening today and there was a chery qq with its blinding rear fog lights on.
i was not in a rush and thus decided to give the driver a friendly heads up so he can switch off his rear fogs because they are extremely distracting to cars behind and it blinds a drivers ability to see ahead clearly.
the weather was fine, there was an overcast sky and the sun had set but the street lights were on and visibility was good. his fog lamps had no reason to be on.
so i went behind him and gave him a friendly high beam. but i figured since i was trying to indicate to him his fogs are on, i switched on my front fogs as well.
he's reaction was beyond my comprehension
1) he drove on for another 300m without reacting.
2) he then proceeded to slow his car down from 80 to 60 to 50kmh..
3) he then switched on his left signal light to filter to the 3rd lane (we were on lane 2) but did not check his mirror and almost crashed into a car on the left, he had to swerve back to avoid hitting that car.
4) he still has his left signal light on and is slowly down to about 40kmh while waiting for a chance to filter left. all the cars going past him on his left were going in excess of 70kmh (how did he pass his lane changing module?!)
5) finally there was no cars (it shld have been a lane change, but he changed lanes like as though there was a give way line. he might as well treat it as a stop line and stop before changing lanes on an xpressway -.-)
6) he then proceeded to the 3rd lane and slow down further to like 25kmh. and he still has his left signal light on and is still trying to filter left to 4th lane for reasons beyond my comprehension.
7) the cars on the left obviously just cruise by without giving way (was he expecting pple to jam their brakes from 80kmh to 25kmh for him to change lanes?)

his rear passenger turned her head around and stared at me. oh i must mention that the rear fog lamps are STILL ON.
9) he completely stopped his car. so we're now on the 3rd lane of a 4 lane expressway and we're travelling at ZERO kmh even though there's no accident or any other reason to stop. oh and he's STILL TRYING TO FILTER LEFT with his left signal and rear fog lamps on.
10) the car behind me horned at him (or me as well?) for stopping.
11) he then moved left into lane 4 halfway even though there were still cars.
12) i gave up, i used wadever half-lane-space was left on lane three and accelerated to continue on my journey and switched off my lights.
13) i still cannot comprehend his actions.
