i haven't tried it, but it seems like a grip on the steering wheel might make that arm bar easier than a free arm (at least temporarily). What do you think?I didn't want to break the guy or the car.
That near hand where I am putting my whole body in to leveraging the front arm off the wheel feels pretty solid.
If I can get the far arm straight. (And I struggled a bit) I can apply an arm bar by pulling the elbow. So if he is hanging on with that far arm. I can start reefing that straight arm bar until he lets go.
