I have a similar situation on my route. About 100 m before I have to take the lane, I'll look back, make eye contact and point right at the driver that I"m going pull in front of. I then make the palm-down "slowing" gesture and take the lane pretty assertively. When I get to the end of the parked cars, I look back again and make a circular "pull through" gesture. When they pass, I give a friendly wave.

I'm trying to convey that I am a good guy, a fellow traveler, and I know what the heck I'm doing. Since I started doing this, I've never had a problem.
