Blocking faster vehicles on the first lane on expressways is a contentious issue.

There are generally two camps.

One camp will say that if there's a vehicle coming up behind you that is travelling faster, you are road-hogging if you do not give way.

The other camp believes if you travel at the speed limit on the first lane, you have the right of way and need not give way.

Enter 'John'. John took the effort to edit a video of his in-car footage documenting his run-in with a driver who belongs in the first camp. John, naturally, belongs to the second.

John claimed he was driving at the speed limit inside the KPE:

Then, a Subaru Forester approaches behind John, turns on its high beam and sounds its horn.

John said that he wanted to filter to the middle lane but there was no space. This keeps up for another 30 seconds. It can be seen in the video that vehicles in the middle lane were travelling at more or less at the same speed with the cars in the first lane, with a silver Toyota Rush even going faster than John's car at one point:

The Forester finally found space to filter to the middle lane to overtake John's car.

But there was no space for the Forester to cut in front of John's car. Note how the Toyota Rush is ahead of John's car.

Unfortunately, the Forester then jammed its brake in front of John's car.

Road-hogging?

Top comments on the video lambasted John for not giving way despite his argument that he was travelling at the speed limit.

Several comments called out John for not keeping left when he was not overtaking. They also called him out for road-hogging.

But somewhere else on the Internet suggests that John may not have been road-hogging.

According to this thread on shared on SG Road Vigilante the ruling on whether travelling at the speed limit is considered road-hogging is somewhat contentious:

While the road traffic rules state that "Every vehicle shall at all times be driven in such manner as not to obstruct vehicles moving at a faster speed" and "Every vehicle which is moving at a slow rate of speed shall be driven as close to the left-hand side of the roadway as possible", it seems that paragraph 4 of the response confuses the matter by saying that as long as you travel at the speed limit you are not committing an offence even if there's a faster vehicle behind.

And then there's this brochure by LTA which doesn't include that factoid about travelling at the speed limit:

There's also a 25-page thread on Hardwarezone arguing what is legal and what is the considerate behaviour. Here's a taste:

Basic Theory doesn't have definitive answer

If you take out your dusty basic theory book, you'll find this:

It doesn't say whether travelling at the speed limit makes you road-hogger.

Perhaps John had every legal right to travel at the speed limit on the first lane, but some times the vehicle behind you may be in a terrible rush -- be it to a loved one's death bed or to their own reckless speedy death -- and it wouldn't hurt to just give way rather than let the situation escalate. Then everyone loses.
