Many people here suggest filtering along the right curb to be a danger.
When I filter, I do so almost 100% along the right curb. If there's a place to turn right, I slow down, make sure the car I'm going past isn't going to turn (driver is not looking where to stop, wheels are straight etc). When on a motorcycle I often filter between lanes, but on a bicycle, if I'm not going along side right curb, when the traffic gets flowing, I have a hard time moving back to the right lane. How do you people handle those situations? Hand signal for turning and going back? Most drivers here go berserk when they see a bicycle outside the right most lane.

The more dense and urban an area is seems to have a lot to do with cyclists' behavior on this. In Chicago, I will certainly split lanes when I feel it's safe, and really, especially when going between meetings downtown during the day, if not for splitting lanes I may as well walk or ride the train - those two options would probably be faster.
I did, last year, have a little accident though - after traffic started at a green light, I cut into a space between two cars in the right lane of the two I was splitting (after signaling my intentions and making eye contact with the car behind me). Turned my head back around to find that the car in front had slowed down significantly - I'm sure it was an extremely important text or Facebook status update. I ended up hitting the back bumper with my front wheel, and laying the bike down in the parking lane - scraped up my knee and elbow and busted my front derailer, nothing worse than that. I've been much more careful since then about lane-splitting and trying to think a few more steps ahead - I also make it a point to steer clear of trucks and buses, both because I don't want to die, and because, really, the thirty people on that bus can totally have the right of way versus the one of me on the bike.
All that said, if I'm not in a rush, I don't mind waiting in a line either.

Nope. Technically, lane splitting means...exactly what it says - splitting LANES. A sidewalk is not a lane. A median is not a lane. A double-yelow line is not a lane. You can only be "splitting lanes" if you are between two lanes. It's all filtering, but it's not all lane splitting. We could argue samantics all day, but the words mean what they mean. Passing cars while riding in the gutter is not lane splitting. It is filtering, or riding in the gutter, or curb-hugging, or anything but lane-splitting. If you split an apple what do you have? Two halves of an apple. If you split lanes there must be two lanes being split. Split something and you get two relatively equal parts by definition:
Verb
Break or cause to break forcibly into parts, esp. into halves...
Noun
A tear, crack, or fissure in something, esp. down the middle...

That is so easy I am surprised you asked. I do it five times a day. Say I am riding 15mph between two lanes of stopped cars and they all start moving. The line of cars are not hooked together like cars on a train, there are gaps between them. Just keep up your speed until you catch up to a gap and merge right into it. In 10,000 tries I have never failed to just merge in, often giving a hand signal that I am moving over but that is irrelevant as there is plenty of space - most drivers leave several car lenths ahead before they even start moving. And now that every A.H. behind the wheel is looking at their phone at a red lignt, the gaps are much larger than before smart phones with viewing screens were prevalent because no one is paying attention to the danged light going green anymore. (I started a thread on that topic - how smartphones have made traffic-jamming at rush hour so much easier for me named "Why I love motorists on their phones").
No, I haven't split lanes. I think it's a foolish practice.

I happened to be thinking about this today on the way home. I live in NYC and my commute takes me through certain parts of Brooklyn. Along about 3/4 of my route, I am faster than the car traffic. That is to say, whether I'm sneaking past a stopped or crawling line of cars or if I find myself between two non-parked lanes of traffic (nor typical), I usually look for a way out of whatever problems arise by proceeding forward, rather than looking behind for a way out. I wonder how many folks who are understandably apprehensive about "lane splitting" commute in places, where car traffic is generally faster than bicycles.

Do I split lanes? Only when I filter a red at 25mph. I also salmon, trout and guppy. God I hate bike lingo.I thought lane splitting meant riding down the middle of the double yellow lines and yes I do that also.
Btw guppy is riding like a newb or a drunk, cars will give you a mile.

You can call a peach an apple if you want to, but when a restaurant patron orders a peach cobbler and the waiter brings them apple pie there will be a discussion. Yes, they are both desserts, and made of fruit, but thanks to the gift of language and vocabulary we generally get the food we order. And I often SPLIT a dessert with my wife - creating two pieces of apple pie. I have never split a slice of apple pie and ended up with half a peach cobbler.
Splitting lanes requires that you ride between two traffic lanes populated with cars. There will generally be cars on both sides of you either in motion or stopped at a signal, wreck, cop, whatever. There would be no reason I can think of to split empty lanes - just ride inside the empty lane of your choice. So defining splitting empty traffic lanes is unnecessary as no one bikes between empty lanes. Therefore it could be said that splitting lanes = splitting motor vehicles in travel lanes. Riding between travel lanes and parked cars, sidewalks, curbs, bike trails, cow paths, ditches, or sound barriers, may be called filtering, but not lane splitting.
For good measure, I will paint one more picture. You are riding down a two-lane highway in the country. Your wheels are on the right fog line (no shoulder). Cars are passing you on the left in the travel lane. Is anyone splitting a lane here? Nope. Everyone is lane sharing. Then you come to an accident and a long traffic jam. You pass 100 cars as you bike along on the right edge of the road. You are still not splitting jack even though you are filtering to the front. But if you ride down the double yellow line BETWEEN those two lanes of traffic...viola! You are now splitting lanes.
Foolish is in the eye of the beholder apparently. Now please excuse me as I must have a slice of apple pie now.

I'm a car as far as I'm concerned when I'm on my bike. I usually ride with panniers now that I've found people are nicer when you have 2 huge yellow bags on the back.
On the unicycle it's another story, I will lane split occasionally, but probably worse is I'll hop from road to sidewalk and back again where it's convenient. I'm slower moving, but much more maneuverable on the uni.
To each their own on lane splitting. Running red lights is a much larger issue.
