lived and drove in Qatar for a few years - there were many 3-lane in and 3-lane-out roundabouts. (also drove in UAE where it was the same). You are supposed to yield to those cars already in the roundabout. Several of the roundabouts also had red-lights (aka "signals", aka "robots"). Left lane is for going left (3rd exit on a 4-way roundabout). Middle lane was for going straight (2nd exit). Right lane was for going right (1st exit). Usually works fine once you're used to it. You aren't supposed to change lanes inside the roundabout, and use your right turn signal when you are exiting (and crossing lanes to exit). If you are maintaining speed and people are yielding and exiting as they should, no collisions.
Trickier roundabouts are those with more than 4 exits, or with additional "slip roads".
On the straight roads, there's no notion of fast-lane or passing lane. But if there's a Land Cruiser tailgating you and flashing their high-beams, change lanes. It's not personal, or road rage, the locals just like to drive fast (and often in any lane in the roundabouts)
Another difference between driving in USA is that green means go, in any direction... whereas in US, left turn is yield on green, unless there's a green arrow.

Yes, but it gets weird if lane three (fast lane) goes straight but lane two (middle lane) wants the third exit or uturn.
If everyone yields to cars on their left, it works, but you gotta keep your eyes wide open and pay attention, and actually yield, all things Americans are loath to do.

As a woman?! As a woman?!
If that's your reasoning why police can't approach you when you stop in the fast lane and block traffic and your excuse for being obstinate and ignorant, get the fuck home, throw away your shoes, get in that kitchen, get pregnant, and learn to shut up.
I bet she says she's a feminist too.

Technically!?!
The bike was in the carpool lane, where travelling faster than other traffic is expected, that's why the lane exists. He was not going inordinately fast, traffic in the fast lane was going pretty slow.
The car crossed two lanes and a double yellow line without looking or matching traffic speed in the lane(s) it was entering. Any one of those mistakes is enough to make this technically the car's fault, all 3 together leaves no question and removes the technicality completely.

100% the car's fault. Not even 1% the bike's fault. He did absolutely nothing wrong.

Being from Kansas, I was taught that this (right lane except to pass) was the law so I have always done it that way. As backwards as Brownbackistan can be, I guess we got that one thing right -- and it seemed to work, I rarely had any issues with having to weave around slow traffic in the left lane.

I did notice that it was a more common problem driving elsewhere in the country, but I didn't know that it isn't actually a legal requirement elsewhere.

Now, living in Thailand, I break the rule all the time (although it isn't a rule here, or at least it is *never* enforced if it is). The slow lane (left lane because they drive on the left over here) is the de-facto "motorbike lane", so 90% of car traffic stays in the right lane all the time. I drive faster than most locals, which ends up meaning that I stick in the fast lane all the time *except* when I want to pass a slowpoke by switching to the slow/motorbike lane.

Probably fake, but the technology is absolutely mature enough.

Self-driving cars are a solved problem. It's a matter of regulation, not research at this point.

In fact, once they reach critical mass, the problem actually becomes a lot easier from a technological standpoint. If all the cars on the road are AI, their behaviour becomes much more predictable, and a highway full of self-driving cars could easily communicate with each other, allowing increased traffic flow and reducing accidents.

Think about a simple scenario right now. You're driving in the fast lane on a multilane highway and your exit is coming up in a km or two. You need to cross 3 lanes, so you indicate and wait for a safe gap. You're completely dependent on the drivers in the other lane to let you in. But human nature being what it is, they might not want to let you in. Even if the first lane lets you through, the outer lanes have no idea what you want until they see you, so you have to repeat this manoeuvre a few times.

But with a highway of self-driving cars? Your car broadcasts its intentions on a localised network, and the other cars create a gap all the way to the exit. You move through and traffic resumes.

You said it. That's how people drive in town...at full speed....without collisions. It would have been perfectly safe if the truck had not accelerated into her spot after she was in the lane, or slowed even just slightly once he realized she was there. EDIT: Also, if that's not a safe distance, what do you call the distance the truck ends up with between him and the first car, WAY less distance than the second car had in front or behind at the start, about one car length, but only because the first car almost pushes the pickup truck trying to escape the semi.
If you are slower traffic, as the truck was, it's the law that you don't belong in the fast lane. Period. "Slower Traffic Keep Right" is the law, not a suggestion. If you've been passed on the right, you are absolutely slower traffic in the wrong lane.
You're nuts, the traffic in the fast lane passes him in the slow lane before they get there. He was NOT going faster than them until he floors it at 15 seconds. Listen carefully to his engine, you can hear him floor it, he's not on cruise control.
She did check, and there was room and she was going faster than the truck, so there should have been MORE room as time went on, she looked forward and made the lane change, then looked again 1/2 way through and there's suddenly an accelerating truck passing her on the shoulder. Then she looks to the other side and sees there's no way to avoid the other truck now, and it's either ram the slow truck or keep moving over and bump the faster truck, which she does.
I'm done. If you don't see what everyone else does, that's not my problem.

Safe to the extent that there was room, with a car length behind and ahead... That is how most people drive in town, or with less room. You do realize this is on a freeway, not in town, right. At freeway speeds, that space was too tight to be safe. Putting a car in that space makes that car immediately at an unsafe close distance to the car in front of it and behind it. At 60mph less than a car length between you is unsafe.

You also still seem to be repeating that the truck had no business being in the fast lane? Look at the start of the video, our truck driver is having to SLOW DOWN to match the speed of traffic in the fast lane. He absolutely is not too slow for that lane.

Finally, per the space available for that lane change, there is no way that car makes a lane change into a space that small, and does it that slowly without ever checking their shoulder, unless they are a terrible, terrible driver.

1. Watch before second 10, he's not closing (4 lines between him and the truck). Watch again starting at second 15, he starts closing. (down to under 3 lines between him and the truck, and less than one between him and the first car). Proof to me he sped up, since you can see the blue truck didn't slow down (passes the other truck at a constant rate).
2. He sped up like a car...brakes work better than acceleration on a semi., he should have gone with the larger pedal.
3. No, traffic ahead seems to go the same speed throughout. Traffic is clear ahead of them, and no brake lights from the truck.
4. Yes, you can hear it. Case closed IMO, and a concession of your point #one. He sped up, blocked the spot (illegal), and caused an accident he could have easily avoided (also illegal, right of way or not), therefore his fault.
5. Yes, definitely unsafe passing on the right. In Cali, it's also illegal to stay in the fast lane if someone is going faster than you..."Slower Traffic MUST Keep Right" signs are everywhere, just ignored....so a bit of a wash that, in this state. Truck and car were doing their thing both in the wrong lane by our rules.
Also important, the truck driver was distracted by being on the phone. Distracted driving is actionable everywhere, no matter what the phone laws in your state are.

I'll just counter with; when the sedan started changing lanes, it was "safe".

The going slow in the fast lane is just a pet peeve, but does end up causing this situation often because of both parties impatience.

What about his being on the phone? It's proven to be as distracting as being legally drunk.

Uhmm... really doesn't matter what you 2 think... sedan changing lanes did so at a time the lane was not safe (even if the truck sped up, a lane deemed "safe" to turn into would be one where sudden changes in speed would not impede your time to react to it safely) and was the vehicle that collided with the truck. The sedan is at fault %100.

As for the truck being passed/slowing traffic in the left lane, SOME states may have a small fine for doing this but the fact that he was passing a semi makes arguing going slow in the fast lane pretty tough to make successfully, he was passing a vehicle. Also even if he was going slow in the fast lane, unless he was going slow enough to be considered blocking traffic (ie 50mph on a 70mph road), you are allowed to pass on the RIGHT but you must do so safely, and any and all accidents that would normally be considered your fault are still your fault.

@newtboy,

I think everyone obviously agrees the truck driver could've avoided the accident. Both the truck driver and car driver could've avoided the accident by backing down.

Your point on the truck not 'belonging' in the left hand lane is absurd to me though, as clearly it is passing a vehicle in the slow lane along with everyone else and merely waiting his place in the line currently in the fast lane to make it past. The car(s) passing the truck on the right hand side are just doing that to cut ahead their place in the passing lane.

As for ramming speed as your last comment, the law where I am is the person changing lanes is at fault, period. If you are changing lanes, and the person in the lane is accelerating. The 'ramming' is being done by the driver changing lanes and ramming from the side. Just rewatch from beginning. The truck driver is SLOWING because the blue truck ahead of him is passing more slowly already than our truck driver is going. 1 car squeezes in between the two. The second car gets there as the truck driver is closing the gap. At the time when both the truck and car are beside each other, more than half the car is still in the right hand lane, but the car driver just keeps on coming. As they approach the 23 second mark you can see the car driver ramming the truck to avoid colliding with the right hand truck as the car is still over in that lane as well. You don't get more clear cut than that.

I think truck's fault because....
First, the truck should not be in the fast lane, it's being passed by traffic, not passing traffic. He's too impatient.
Second, the truck intentionally speeds up to block the car. When it started the lane change, there was room. When you change lanes, you look sideways to be sure there's room, then you move over while looking forward. If someone speeds into the space and hits you from behind after you start the lane change, it's THEIR fault unless you slam on your brakes to make them hit you.
Third, the truck, trying to block the car, moves WAY too close to the next car, tailgating insanely. Watch the black car speed away terrified.
Fourth, the truck passes the car on the shoulder, them moves back into the lane slightly squashing it. The truck knew the car was there the whole time but just refused to brake.
Fifth, the truck was speeding. The truck speed limit is 10mph below the car speed limit on freeways, and the truck was going faster than the speeding cars, so almost certainly speeding by over 10mph.
Sixth, and indisputable, the trucker was on the phone, making him at fault as much as if he was drunk, no matter what he did driving.

As I see it, the car was less than safe, but the truck was an intentional dickhead that STARTED the film by driving badly, and ended with an accident he'll pay for. It's on film, he saw the car changing lanes and sped up to block it refusing to let her merge, passed it on the shoulder after it had passed him and entered the lane, and hit the car on purpose because he refused to hit his brakes/didn't want to be passed again. If I was on the jury, I would put it (EDIT)98% on the truck. He had every opportunity to avoid the accident by hitting the middle pedal just a little, but instead stood on the little pedal and seemingly thought to himself "Ramming speed!".
