As I was not driving too close to the kerb on the left, a motorcyclist managed to squeeze in between the empty space between the kerb and my car. Since I am filtering into a main road whereby the traffic is coming from my right, it is only naturally that I keep a lookout for vehicles coming from that direction. I did not notice the motorcycle on my left until I looked in front again after confirming that traffic on my right has cleared. I filtered into the second lane to create clearance space between my car and the motorcyclist. The motorcyclist filtered into Sims Ave concurrently. If the traffic on the main road is busy, I may have no choice but to filter into the first lane and the motorcyclist could have put himself in a potentially dangerous situation. Actually, readers may recall that we are taught to filter into the first lane at the driving schools.
In the event of an accident, a motorcyclist will get hurt more easily than a motorist for obvious reason. It would be unwise for a motorcyclist to put himself in a dangerous predicament just to save a few seconds.
