We still have the cop on the scene commenting on intentional damage:Unless Lash somehow caused Harry to damage the car in such a way that it looks like another car was involved.
Of course not. It's just that since we know Lash can make a fake person look real to Harry, and as we see with Hannah, can alter what people hear, we then get to ignore literally anything at all that we don't like, under the umbrella of "Lash made Harry think something else."
