    I wouldn't have picked up a calculator because I could do it quicker in my head than it would take to type the numbers in. I remember doing a 400 question 1 hour multiple choice test when I joined the army (maths, English, and logic); you know one of those ones that gets harder and harder as you progress through the questions. I managed to finish it with 5 minutes or so to go. I put my hand up, one of the guys came over and said "You know I can't help you with any of this", I said "I've finished". He was shocked, he'd never seen anyone finish it before. The first half of the test was easy, the answers were obvious (to me at least). The second half was harder, but knowing how to instantly rule out wrong answers, for all types of questions, is the key to going quickly. If you pulled out a calculator for every maths question you'd never be able to finish. I think one of the goals of the test was to make it very hard to actually complete the test and get a good score (you were penalised for wrong answers). I still managed to get over 370 points.

I looked at the problem, realized I might need to get some scratch paper to work on it, then saw "You can use a calculator." and promptly opened up a calculator on my computer. Why should I do something mentally if it can be done more accurately by a machine?

    See, I've worked in a build lab before, and almost everything was automated, because if a human had to give input, that input could be wrong, and it could break the build. So we attempted to automate absolutely everything that we could. Sure, I could eventually do (45*75)/25 in my head... but I also might come up with the wrong answer.

Anyways, I would bring it to the teacher, explain my logic, and reasoning, and usually got a corrected grade for that question... probably more so, because I could explain my argument logically and rationally than for anything else. (I was like 12-ish, give me a break, I don't remember details.)

    Of course, in college, I had a TA mark a problem dealing with induction that I did as wrong. I brought it to the professor, and he noted that it was indeed correct, and he ended up scolding the TA for marking my test wrong. Oddly, it was kind of a fallacious argument that the professor made. Basically, like, "I know this student is good, and is likely going to have the right answer, and you're in the wrong for not recognizing that." But then, the TA marked me wrong because I didn't fit his happy rote-memory version of what was correct, rather than me actually being wrong... so in a way, the TA kind of did deserve the scolding because he was grading brainlessly...

    Regardless, California is the "exceptional" state that everyone uses as an example for "sometimes lane-splitting is tolerated". However, the MSF and any lawyer will tell you that outside of California, you risk being ticketed for lane-splitting, since it is incredibly unlikely that any other state tolerates lane-splitting.

    snowgirl, I truly respect any other rider. I'm only offering advice because, thru the fog of the Internet, you seem to be a newish rider who is just reciting some recently taught doctrine.

    My sincere apologies if I've misinterpreted our relative levels of experience.

    You have underestimated my experience.

    That is the exactly the problem with this mindset. The way you should react to a driver who does not see you (common) is very different from the way you should react to an aggressive/malicious driver who doesn't like you (rare). If you assume the rare case, you may be setting yourself up for an accident in what is actually the common case.

    I'm entirely confused here. Assuming that a driver doesn't see me, vs that driver will attempt to hurt me, is a difference only in INTENT not in deed or action. If a car pulls out in front of me, then it doesn't matter if they didn't see me, or they were trying to intentionally harm me, because I'm still dead. So, let me ask you, why shouldn't I assume that just because a driver sees me, that they won't pull out in front of me? I've heard tons of stories of "the person was looking RIGHT AT ME when they pulled out in front of me!"

    And at that point all of the intent of the driver in the world is meaningless. Perhaps they didn't register what was going on, perhaps they thought they could make it, perhaps they REALLY DID want to kill you. But none of that matters, because you're the one paying the price.

    That means that if someone is standing at a light to make a left-hand turn, or approaching a light to make a left-hand turn, or even waiting on a light for a left-hand turn, then as I'm approaching to go straight through that same intersection, I ensure that I am traveling at a speed such that if that person chooses to make that turn for any reason or intent possible that I will be able to stop in time. Even if that means that I'm creeping up to that intersection.

    According to Wikipedia, the only state that really seems to allow lane-splitting (and indeed, is the universal example of a state that allows lane-splitting in the USA) is California. In general, lane-splitting in the US is illegal, while it seems that it is generally widely legal in Europe.

    Actually, that wiki article states that lane splitting is illegal in "many states", but it gives no reference, and the only states they specifically mention are Colorado and Nebraska.

    If you'll read my quote again, "the only state that really seems to allow..." (emphasis added for the reading impaired) What does this mean? It means that no shit, I saw the Colorado and Nebraska text. Yet they were equivocal about if those states actually allow lane-splitting or not. Why treat them like you can't lane-split? Because the text also explicitly states that New Mexico has no laws against lane-splitting either, but it does have plenty of laws that mean that lane-splitting would not be legal, and legal precedent is that lane-splitting is a violation of other laws.

    Searching for "colorado lane-splitting", I found a forum where people say it's illegal. And a lawyer's webpage stating that lane-splitting is only legal in California. In fact, I found that apparently there was supposed to be an initiative in 2008 to make lane-splitting legal, Ballotpedia says that no such initiative exists.

It would be incorrect to talk about the gravitational attraction when it plays a close to negligent role in day to day interactions of such a system.

    Why take such a crazy and over the top assumption? Because it's your life on the line. An ex-boyfriend called it the "bash value". In a nut shell, if two vehicles collide, the one with the higher bash value wins. So, little cars have to worry about any and every collision with an SUV even if it is the fault of the driver of the SUV, but in a motorcycle, you have to worry about any car hitting you, because that little two-door smart car still has more bash value than you do... This translates to: yield and give the right of way to everyone else... because if you try and take the right of way, and they accidentally don't notice, or something like that? You're fucked.

    And thus, the advice to drive like everyone is out to kill you: it keeps you in a mindset that doesn't let you get into a situation where a careless driver will accidentally run you over.

(If someone is tailgating you, you're better off being behind them, where you can choose to observe a safe following distance. If someone is drunk, who knows what the hell they're doing behind you, and if you stare in your rear-view mirror to be safe there, you're probably going to be getting yourself in trouble ahead.)

    Last one, I remember hearing that stop-and-go traffic is particularly dangerous for motorcyclists, and that is why some states allow them to cut lanes (NOT ALL STATES LET YOU CUT LANES), because the danger to the motorcyclist is actually greater in the stop-and-go, than them driving through the traffic between the lanes. I actually only know of California as a place that allows lane cutting, but there is no reason why it couldn't be elsewhere.

    Another odd rule that motorcyclists get to "break"? In Washington state motorcyclists do not have to maintain any amount of insurance on their motorcycle.
