Know what I'd do? I'd probably ride very slowly on the sidewalk until I got out of the logjam, being anal-retentively careful about cars backing out of driveways (but there shouldn't be any, since their driveways are blocked by the backed-up traffic).
I know, I know. Sidewalk biking: bad.
But.
That's what I'd do. The good people of Mountain View will just have to deal.
Or walk the rig for the few blocks where traffic is a problem. For extra exercise, maybe you could run with your bike, CX style.
That would amuse the kiddos, wouldn't it?
