So the earlier example with a car doing much the same has been corrected. Now they have data that shows a bike can do something similar at an intersection. I imagine it will be pretty trivial to produce code that lets the car progress through the intersection slowly, while watching the bike to make sure it stays within a box.
One thing's for sure, a car that refuses to go until the cyclist stops moving or takes their turn is hardly creating a dangerous situation.
It does raise another interesting point though. What is it that US road designers have with four way stops? They place them everywhere, while the rest of the world happily gives bigger roads priority and use yields to allow traffic from side roads to merge. If the roads are very similar in traffic volume, use a roundabout.
