We sure agree re: lanesplitting!
Cars have more rubber on the road than bikes, so they can (sometimes) outbreak us. Much worse, if we're camped behind some guy's bumper, an idiot in a cage coming in from the rear may fixate on the larger target ahead of them and ignore the smaller target (you on the bike) between.
Either way, the solution is "no-be-there-fu". Make your own lane down the middle

Since moving to the Seattle area I've seen things I flat can't believe. One BMW bike had hard luggage about 2.5ft wide each side. Looked like Rosie O'Donnel's backside goin' down the road. Absolutely impossible to thread any needles on THAT piece of crap so if it all goes to hell in front of him he's toast. Even the guys on thin bikes don't have any experience with threading needles so they don't have the skills to use their best possible escape routes when it all goes rodeo.
Another bizarre thing I've not experienced much in 20 years on bikes: cagers acting like bullies.
In California, any cager who pulls that crap will only see the bike squirt forward and be gone. Ain't no fun to play with so they eventually stop.
Up here, we're legally "trapped" and there are jackarses who take full advantage...in the rain mind you.
Swear to God, next legislative session there's gonna be a brawl over the yearly pro-lanesplitting bills.
