Hmmm...
We have a few 100% T intersections with lights. And, at the top of the T, it doesn't impact bicycles in a bike lane one bit. What the cities should do is draw a straight line for the bike path across the intersection to denote the light doesn't impact the bikes. Perhaps mark "Bikes Yield" on the pavement.
WATCH OUT FOR TRUCKS?
There is a similar T + driveway in Springfield that I regularly pass, and I usually stop, but find it a bit annoying, especially if I go through there in the evening when all vehicles around me are clearly visible.
Unclipping isn't the worst thing in the world. I'll do it on occasion.
