The Guiding Principles and New Rules document is now in effect.
This question is just academic for me, but it's something I've been wondering about, and I don't remember it coming up in driver's ed (a long time ago for me, admittedly).
Two cars are traveling in the same direction on a 3-lane highway, one car in the far right lane and one car in the far left lane. They both want to merge into the center lane, but they are situated such that if they do they will collide. Who has right-of-way?

I would think it'd go to the car in the far left lane, because if we remove the simultaneity from the timing... if car R switched into the center lane first, car L has the right to overtake him, whereas if car L switched first, car R does not (in general).
I seem to remember something about the left lane only being for passing, but no one follows this rule if it's true. As for what you are talking about, that's exactly the reason why I never change lanes with someone on the same latitude as me. I don't think there is a right of way in this situation, as traffic school wasn't THAT long ago for me and I don't remember anyone saying anything about it. Common sense right of way?
I'm thinking the driver in the right hand lane, because legally you are supposed to remain in the right most lane possible, so if you are in the far left lane with an empty space between you and another car, and the car in the right most lane possible needs to merge left he has the greater need.
However I imagine for all practical purposes if two cars collided under these conditions the police involved would declare both drivers "at fault" for unsafe driving.
It depends on who is ahead of who, on paper you can say "they are both right next to eachother" but in practice, if Car A is ahead of Car B and Car B merges in to Car A at the same time, Car B's center of mass (engine) will push in behind Car A's center of mass causing him to spin out, making it Car B's fault as his actions caused another driver to lose control of their car to what is considered 'no fault of their own'.
For example: In Wisconsin, it's perfectly legal to pass on the left or the right, and pretty much chill in any lane as long as you are not obstructing traffic.
Whenever there is a car parallel to me in whatever lane, I *always* hit the breaks and have the car speed up relative to me, I *hate* having cars next to me when I drive. I can't see their blinkers and who knows what they are planning.

I know that in Texas at least, the driver in the right lane has to yield to the driver in the left lane. It's because of visibility.

Just for everyone's info, since I was not taught this in driver's ed: The left lane is only for passing. You can get a ticket if you continually drive in the left lane. It doesn't really get enforced in congested areas (there is technically always someone to pass), but if you are for example driving on a 2 lane interstate by yourself you can and will most definitely get a ticket if you are in the left lane with no cars to pass. This is true nationally and is not specific to any particular state.

Can you cite that?
In Illinois I know this to be true, but in Wisconsin, I have passed speed traps left and right on I94 and never got pulled over once. There is a sign on the WI/IL border that informs you that in the state of IL, staying in the passing lane is illegal.
This is from the Wisconsin DOT. There is no mention of being required to be in the right hand lane unless you are on a two lane road with traffic that is in the opposite direction (stay out of oncoming traffic, duh)
Passing another vehicle
Usually you are required to drive on the right hand side of a two-lane street or highway. One of the occasions during which it is legal to drive on the left side of a two-lane road or highway is when you are legally passing another vehicle.
When you pass on a two lane road you must leave the right lane early enough and remain in the left lane long enough to pass without interfering with the other vehicle. It's your responsibility when passing to make sure it's safe. It is the other driver's responsibility to give way and let you pass without speeding up. Of course you cannot pass in a no passing zone designated by signs or a solid yellow line on the pavement on your side of the center line.
Take extra care when passing bicycles. They must be given at least three feet of clearance.
It is legal to pass a bus stopped on the road, taking on or letting off passengers unless it's a school bus. But it is not legal to turn right in the intersection directly in front of the bus. If you need to turn right, wait behind the bus until it moves away.
You may not pass another vehicle within 100 feet of railroad tracks, a tunnel or an intersection, unless there are two or more lanes of traffic in your direction.
Depends on Jurisdiction. Here in MB, common practice (and Law, at least outside of Winnipeg) is that slower traffic keeps right, so theoretically the vehicle on the left should be moving faster and would merge forward of where the right vehicle merges.
If a collision occured they'd probably be looking at a 50/50 at fault situation.

This is not true of the majority of states sadly. God I wish it was.

Is there any such thing as a national driving law? I thought the only such things were for commercial vehicles ever since they repealed the national speed limit in the 80s. If there are, where would you look up these rules?
No there isn't. The privilege to drive is regulated by the state. We can have speed limits of 130MPH if we wanted. The problem is that the federal funding for the interstate freeways comes with all kinds of strings attached, so they tend to munge things in like 55MPH speed limits or they don't get the extra cash to fix the roads

That's how a cop explained it to me anyways.

I don't think this is true in most places: http://www.mit.edu/~jfc/right.html
I know in California I've never been or seen anyone pulled over for being in the left lane without traffic in the right lane.
It's the law in Manitoba, Canada, which I didn't know until I was pulled over, warned, and then went home and actually looked it up myself.
This is not true in Michigan.

Ah, I was assuming the discussion was limited to the United States since nobody had mentioned otherwise. Consider my statement suitably amended.
