Barehands? I'd find it difficult to believe if anyone could manage that. You'd have to choke the thing out which means holding on as it bucks around. Even professional cowboys have trouble doing that and they don't have to focus on choking the cow.
Maybe if you could sneak up on it while it's sleeping and could use a rock or something. Doubt bare hands though.
I agree with above on underestimating what is effectively an economy car that can decide to hate you and is far better at being able to parallel park on top of your body if you're going in without a weapon.
