The whole idea of dismounting and walking just terrifies me, frankly, if it's the kind of intersection I think you're talking about, the kind that's typical in our neck of the woods.
You've transformed yourself from a vehicle in traffic - albeit a slow-moving vehicle - into a pedestrian, in a spot where there are no pedestrian facilities....Catrin, you've learned so much so fast, I think you're much safer to postpone your commute for a few months until you're confident stopping and starting in traffic. Trust that you will get there and value your safety enough to wait.
I picked an intersection at random that can't be too far from you - so these city slickers can see what I'm talking about.

Correct me if this isn't the kind of thing you mean.
