High winds per se won't deter me much from lanesharing, but certain conditions might. For instance, if a tall or top-heavy vehicle is clearly getting buffeted by a cross-wind, I'll refrain from sharing a lane with it and wait for an opening to weave around it with a greater cushion when I can. In a stop-and-go highway jam situation, I'd find it more unnerving to be going at a very slow speed in winds and would rather maintain some speed and momentum which (maybe it's my imagination?) actually helps me control my line better.
Yeah, I hear you about the truck thing. I always watch out for when I can see a truck is being bobbled. In normal conditions, even with slight wind, I always split too. In normal conditions, if traffic is moving at 30mph on the BB, I'd have no problem going between the cars at 35-40mph. I think speed definately helps keep your line and so that's why it was so unnerving on tues. That day I only saw two other bikes on the bridge. One was splitting and the other was also sitting behind a car. I usually see three to five bikes all splitting during that commute. I think to keep my line I would've needed to go so much faster than would've been comfortable. It was a very uncomfortable situation all around -- I'll be Barting next windstorm

I think a little speed helps, but there are many variables to be super careful of.
I came around PotreroHill on the raised freeway into the city. In parts there are wind channels that can blast you almost into an unexpected lane change.
I was coming from Sf State down Ocean towards the 280 and OMG! That's where the wind is produced, I swear it's totally undiluted around there. I was sitting at a light and put my right foot down and had my left foot resting on the peg. Out of nowhere, a wind gust hit me so hard I had to stomp my left foot down to keep from toppling. I'm sure the people at the bus were a little concerned for me
