It seems like a tragedy, but actually it can be a boon as long as you travel in neither the leftmost nor rightmost lane. The majority of the traffic entering your buffer will be exiting your buffer out the other side as soon as they can, so you can just chug along at a (greatly reduced, but) consistent speed. Meanwhile, the traffic to either side of you is in standstill, paralyzed by your bow wake.
It's wild to me how often the left lane is not the fastest lane.
I've had times where the right lane ends up being the fastest. On I-5 near Woodburn, OR, it's 3 lanes. So many drivers, including truckers, will often stay out of the right lane entirely to avoid being caught up in traffic coming on/off. Meanwhile, the left lane is going 5 mph under the limit because there's a left-lane camper somewhere miles ahead. So I can fly past everybody in the right lane because there's actually barely any traffic coming on/off and everybody is avoiding the right lane for no reason at all.
The section of I-5 between Portland and Salem is absolutely psychotic, and I have never been able to reason out exactly why. It consistently has a left lane jammed with angry people going at or below the speed limit, a fairly normal center lane filled with cruisers, and a mostly empty right lane with the occasional big rig and regular very-high-speed cars expressing their frustration with the left lane by going 25+ mph over the limit in the right lane.
I know that's what you basically just said. Just venting. The driver behavior in that section of freeway confounds me, and I do not know what the underlying cause is. It is otherwise an unremarkable bit of interstate like any other.
The alternative is that you're stuck going 10+ mph under the limit because of a left lane hog.
Banning passing on the right only works if keep-right-except-to-pass laws exist and are thoroughly enforced. Most states in the USA don't have keep-right laws, and those that do, it's never enforced, so many people don't even know it's actually the law.
EDIT: US-26 westbound immediately outside downtown Portland is notorious for left lane campers. The limit is 50 mph, but without fail, there's some moron going 40 mph in the left lane. You wanna go slow? Fine, but do it in the right lane where you belong.
AFAIK all US states have some form of "keep right" or "slow poke" laws in various forms that distill down to keep right, except to pass.
So the laws do exist, they just are never enforced. Even when said left lane campers cruise by state patrol, I never see them stopped. Hell, I rarely see them stop people going 15+ over the limit either so not actually sure what they're doing.
Its not against the law in any US state (a quick search seems to back this up) to pass on the right. With one huge gotcha, it must be "safe" defined in various ways.
OTOH, most states have a stay right except to pass, slower traffic keep right laws.
Which means, that unless the person to your right is weaving through traffic, driving on the shoulder, or a few other bits of unsafe behavior, if someone passes you on the right your likely the one violating the law by not moving right when your not actively overtaking/passing someone.
There is not a single state in the USA where using the right lane to pass slower traffic in the left/center lanes is illegal. It is allowed everywhere.
It's not the fastest often because it's oversubscribed and people do not understand that the car has a 3rd, mostly underuntilized, state of neither pedal depressed (ie "coasting") ... so they create cascading braking pileups ...
To be fair, some (automatic) vehicles have such tall gearing that coasting will not slow you down if on a flat, let alone downhill. I've driven a few, and I can't stand them. You have no choice but to tap brakes.
I much prefer cars with short gearing for better engine braking. I continue to choose to drive a manual party for better engine braking.
So many people don't even use regular cruise control. They'll have nobody in front of them for miles and their speed yo-yos between 60 and 65 mph. And if you pass them because your cruise is set at 66 mph, they'll speed up to match, but then eventually decide to pass you, get in front, and slow back down to 60. The only way to end the stupid cycle is to go 70-75 mph until there's at least 1/4 mile between the two of you.
The adaptive cruise control in my Subaru rarely coasts. It isn't smart enough to see a gap slowly narrowing and start coasting, and it isn't confident enough to temporarily allow the gap to be smaller than the setpoint while it coasts to recover the gap. So it brakes and wastes energy, and I don't use it.
Truckers sometimes have a good reason to do that -- they can't brake or accelerate as quickly as a small vehicle, and thus can end up going very slowly if they stick with the right lane. To a driver going 3 exits down the 205 it's not a big deal, to a truck driver doing the same they may be at the end of a long haul up the I5 and every minute starts to count since it can affect their pay. And if you can avoid hard braking/hard acceleration in the right lane, that can help your fuel costs quite a bit since slowly coasting behind someone doing 5 under in the left lane is more efficient than jerking around in the right lane.
There are plenty of ramps on I5 and 205 that I merge to the left for because I know they will spill into the right and (when it exists) middle lanes. Because of how traffic also reacts to brake lights (some people brake too hard even when they have sufficient distance to let off the gas and coast to a slower speed) it seems like it ends up making my experience through those stretches a bit better.
Ultimately, any individual behaviour is largely irrelevant, it's what the whole mass of cars moving along does that affects things the most. Often you don't want to be the (significantly) odd one out regardless of the situation.
That's not a good reason, those truckers are just assholes. I'd like to see the authorities enforce the law and fine them heavily. Put them out of business.
I've done a few tours around the world on the interstate system, so I've seen my fair share of truckers. Yeah, some are assholes, but there are stretches and routes where their behaviour makes sense, even if I don't like it. It's on them for how they behave, but understanding why they behave that way can make it simpler to deal with them in real life. As real, squishy people, not a system of rules.
Would I love to see CHP or OHP fine every left lane trucker in the 'no trucks in left lane' zones? Hell yes, but until that happens, I understand the trucker behaviour.
Being a bit more nuanced, I dont mind a trucker in the left in a 2 lane section (they're likely trying to avoid bad interactions with merging cars from the right) ... but it does bother me when its 3+ .
This is what most frustrates me about driving in Florida. The right lane is nearly always the fast lane, yet is the lane with most 'events.'
When asked, they'll say they feel safer in the left lane because they don't feel safe having to deal with people turning out and merging. So you get instead people driving fast in the lane meant for pulling out and merging.
> as long as you travel in neither the leftmost nor rightmost lane
What I really hate, however, is that plenty of people will cruise in the center lane but still not leave a decent gap between them and the car in front. They effectively turn a three lane freeway into two one-lane freeways by hobbling the ability of anyone else to switch lanes. The freeway moves way smoother when there is a modest, predictable speed differential between each lane so that people can find their way into the next lane over without having to force the issue.
