+1 I was riding home from work one night a couple of years ago on a street with a bike lane. All the cross streets have stop signs and many of the intersections also have partially obstructed views - i.e. trees, hedges, fences, etc. Some a-hole on a bike blew a stop sign right in front of me and I had no time to react and plowed into his rear wheel. We both went down but I think he got the worse of it and may have even broken his collar bone. I didn't even get a chance to talk to him, though, as he took off as I was collecting up all the parts of my headlights that had come off my bike and separated into many pieces.

As for the T-intersection, there is one on a route that I ride a few times per month and I generally stop if the light is red. I 'spose I might roll through if there were no other vehicles.
