After reading farkman's subsequent posts, I believe we have these intersections as well. The intersecting cagers get better view of (car) traffic if they push their car all the way over the part of crossing where I am supposed to be riding. So that is what they frequently do, unless there's a constant flow of cyclists. In that case they seem to understand better that bike traffic is traffic as well.
I seldom go round the front of such cager. They may make a desperate last second attempt to get out of the way. They usually cannot reverse, because there's another car behind them. I sometimes ride full blast right to their window, stop, lean my elbows on handlebars and just stare them until they get their piece of scrap metal out of the way. Or ride full blast to their window, brake and go round the back, hitting car trunk audibly with my hand on the way.
