Mr. Murphy, I'm not quite sure how to answer that question. I don't know why it causes people to refuse, whether it's because they're concerned about going over, or they're concerned about being in an accident, but anything that can assist in taking away that incentive may be helpful. But you always have to be concerned with going too far, and then infringing into self-incrimination, as well.
But for the most part, if there's a greater punishment for refusal, I don't know what, if any, effect that's going to have, because I don't know why people are refusing, to be perfectly candid.
