kick in their quarter panels as you shove your way through.
actually those drivers should all get a ticket for blocking the intersection. Call police on their local line (not 911), have enough people complain about it and the police should do a crack down on that sort of bad mannered driving.
we actually have the middle of the intersections painted with yellow crosses in the downtown area and anyone caught blocking in there can and will be fined for just that.
I normally would be very irritated by people consistently blocking the intersection like this, but I think this intersection is sort of an exception. The light for the cross traffic is pretty far from where the blockage actually occurs, and it would be pretty hard to judge whether it is safe to proceed without blocking Comm Ave. I can give the motorists a pass one this one. I think the real problem is too many people getting onto Storrow Drive all at once, and poor traffic design.
