Sony a7R Mark III vs Nikon Z7 AF comparison

Can someone tell me how does those two photos compare.

As a bike rider without going into any big theory about G, it is clear that those two guys are not going at the same speed. In the Nikon one it is clear that he is already riding at a certain speed and taking a turn at an angle because of the speed. In the Sony one it is as if he is just starting. However he does  seems to take to some speed to be honest to take the turn but nothing compared to the Nikon one. So the lighting and place is about the same, but until they get a repeatable subject moving at exact same speed and direction that test is flawed. The size of the subject is also questionable. The bigger your subject (Sony) covers the frame, the less like likely your AF will focus on the background.
