Respectfully, I disagree. Where is the data that shows lane splitting or filtering is dangerous? I do it regularly in busy southern California traffic and feel safer than I do sitting in stop and go traffic. Most car drivers here seem to be used to us splitting on bikes, and many many of them move over to give us even more room as we go by.
Two of my dislikes however are really loud bikes that startle people as they pass, and high speed lane splitters. There will always be the outliers that spoil it for the rest.
Get out of California and you will find plenty of examples.
