It does make it harder to cycle round, but that is where people have a plan.
Bath Buildings, weekday evening. No cars in the ASL, yet rather than wait patiently, this woman decides to run Gloucester Road -2 lanes of car traffic, one bus-lane on the right of this picture, and cars on the left waiting to turn into Bath Buildings.
She lives, and was passed about 20 seconds later, her pushing her bike up Nugent Hill, before she'd even got past the one-way cars-can-contraflow stretch.
If she were fit, she could have waited, cycled across on green, and got up the hill without having to risk the passing cars, faster.
But think about it. By running the lights, then walking up the hill, she gets to get up the hill fairly quickly, without needing to be fit. Just brave. And for that, we honour her!
