With a speed limit of only 25, and with light traffic, I'd just take the other lane.
I do that sometimes on my route, where I am on a divided road (two lanes going in one direction, speed limit of 30 mph, routinely violated by drivers, however).
Most drivers are making a right turn on this stretch to get on a road that takes them downtown. So I just ride in the left lane so they don't have to pass me, then move over again.
Unconventional riding, but in these conditions it makes sense. Sounds like it would work for you, too.
