>I’d also like to add that I think lane splitting is wildly dangerous and dread driving in California. Surely motorcyclists die from this every year? So it's a bit contentious, but from what i've seen, it's safe as long as it's done safely, which is a dumb sentence, but let me explain: There are really 2 things that people talk about with "lane splitting": * Filtering - moving up between stopped cars at a light to the front of the pack, and then driving away when the light turns green. Generally you aren't passing other moving vehicles when filtering, or if they are moving it's a few mph at most. * Lane Splitting - This is when you are driving between lanes passing other vehicles that are moving. Filtering is considered to be safer than not filtering. It reduces rear-end accidents (people tend to "look through" bikers, and will pull up behind the car in front of them like they aren't there, there's also your "normal" rear-end accidents, but they are much worse for the biker...), it reduces traffic (bikes accelerate faster, so getting them out front is helpful to reduce the rubberbanding traffic), and it's obviously nicer for the biker as they get where they are going quicker. Splitting on the other hand is contentious. On the one hand I believe there have been studies done that shows it reduces fatalities. But at the same time it does actually increase accidents, but those accidents tend to be much less dangerous. Since a splitter should only be going 5-10mph faster than the cars, any impacts should be kind of like 10mph impacts, and are much less dangerous (obviously still dangerous, but much less than being rear-ended, getting left-turned into, or rear-ending something, etc...). And it greatly reduces low-speed rear-endings while sitting in traffic (a fairly low-speed fender-bender can be a lot worse when a small bump can throw you backwards off the bike and onto the ground!) But splitting does have other benefits other than safety. It's obviously much faster for the bikers, reduces traffic for everyone, and therefore reduces environmental impact in many cases (less cars AND bikes idling in traffic). And there are also second order benefits that it encourages more people to ride bikes, which just increases the above benefits even more. Still, it's my opinion that both Splitting and Filtering should be fully legal everywhere. It doesn't really impact drivers or those who don't split to have it be legal beyond a possibly slight increase in small accidents (there's an argument that if it is much more dangerous then it could increase healthcare costs for everyone too), and those who are okay with the risks can do it. And obviously at no point should anyone ever be flying between cars going 20mph+ faster than the cars around them. That's not safe splitting, and that's not what I want either.
