close to any other cars okay and that's a different triple cost so I'm not talking about reinforcement running everything is differentiable everything is computable I don't need to try anything I mean I don't need to like estimate gradients of stuff by by trial and error everything is differentiable so the part name of course is that this this model of what cars around you are going to do is not deterministic right there's a lot of things that cars around you are going to do that you know you may not predict
