How about you get out of that lane while cars are merging? One of my pet peeves is drivers just sitting in the inside lane and making cars merge all around them. I get it during rush hour traffic but when there is light traffic just move over and give the merging drivers room.
As far as I know you don't have to let someone onto the highway, it's on them to find a safe spot to enter and get in appropriately with enough safety distance between vehicles. This is especially true if they have a yield sign.
Baggsy is correct, there is NO legal obligation for traffic to change lanes to make room for people merging - it is the sole responsibility of the person entering the highway to not only accelerate (Which is problem number one as that simple step is lost on about 60% of drivers) and then find a spot once up to the flow of traffic (which, when you don't F'ing ACCELERATE is a challenge) and then merge in.
Yes, it's common courtesy to move over if possible, but it's also frustrating as **** to see someone coming down an onramp with a a kilometer of space *ahead* of you to merge easily, only to see them putter down the onramp at half the speed of traffic flow, not paying any attention until they're nearly out of space, still not accelerating, and only when they're almost out of real-estate down they THEN do they look in the mirror and realize it's time to merge.....and then suddenly it's
everyone else's problem that there's nowhere for them to go.
Then they give you the finger because guys like me at 70 feet long often
can't move over because of traffic in the other lane...nor is slamming on the brakes and losing 50% of our speed & momentum (that can take kilometers to rebuild) an option.
But it's all my fault...and then the idiot goes on a forum or writes a comment to on FB complaining about how the idiot trucker "almost ran me off the road".
And if we were left with no other option BUT to slam on our brakes to let the idiot merge, now "that idiot trucker was doing 50K on the 401 for kilometers and traffic had to swerve all over the place to avoid it!" is the next story.
